-Subject: [PATCH 1/9] vmware_guestdump: Version 7 support
-
-ESXi 9.0 updated debug.guest format. CPU architecture type was
-introduced and several fields of the header not used by the crash
-were moved around. It is version 7 now.
-
-Make corresponding changes in debug.guest parser and keep it
-backward compatible with older versions.
-
-Fix comment and log messages typos as well.

-Date: Fri, 2 May 2025 13:18:17 -0700
-Subject: [PATCH 2/9] Fix incorrect task state during exit
-
-task_state() assumes that exit_state is a unsigned long, when in
-reality, it has been declared as an int since 97dc32cdb1b53 ("reduce
-size of task_struct on 64-bit machines"), in Linux 2.6.22. So on 64-bit
-machines, task_state() reads 8 bytes rather than 4, and gets the wrong
-exit_state value by including the next field.
-
-This has gone unnoticed because directly after exit_state comes
-exit_code, which is generally zero while the task is alive. When the
-exit_code is set, exit_state is usually set not long after. Since
-task_state_string() only checks whether exit_state bits are set, it
-never notices the presence of the exit code inside of the state.
-
-But this leaves open a window during the process exit, when the
-exit_code has been set (in do_exit()), but the exit_state has not (in
-exit_notify()). In this case, crash reports a state of "??", but in
-reality, the task is still running -- it's just running the exit()
-system call. This race window can be long enough to be observed in core
-dumps, for example if the mmput() takes a long time.
-
-This should be considered a bug. A task state of "??" or "(unknown)" is
-frequently of concern when debugging, as it could indicate that the
-state fields had some sort of corruption, and draw the attention of the
-debugger. To handle it properly, record the size of exit_state, and read
-it conditionally as a UINT or ULONG, just like the state. This ensures
-we retain compatibility with kernel before v2.6.22. Whether that is
-actually desirable is anybody's guess.

-Subject: [PATCH 3/9] Add multi-threads support in crash target
-
-Previously, only one thread is created in crash target by [1]. And this one
-thread will work as the common container for different tasks whenever
-"set <pid>" to it. Its tid number is 0 and will never be deleted.
-
-In order to support multi-stacks, we enable multi-threads in crash
-target. Each thread will represent one stack, and "info threads" will
-list all available stacks, "thread <id>" will switch to it.
-
-Since multi-stacks is task binded, each task switching will trigger
-a thread delete of those tid number other than 0. In addition, we will
-pass the tid number to each arch's get_current_task_reg(), in order to
-retrive the regs value of the specific stack.

-Cmd bt will list multi-stacks of one task. After we "set <pid>" switch
-context to one task, we first need a bt call to detect the multi-stacks,
-however we don't want any console output from it, so a nullfp is used for
-output receive. The silent bt call is only triggered once as part of task
-context switch by cmd set.
-
-A array of user_regs pointers is reserved for each supported arch. If one
-extra stack found, a user_regs structure will be allocated for storing regs
-value of the stack.

-The current issue is only observed on PPC64le machine when loading crash,
-E.g:
-  ...
-  crash: page excluded: kernel virtual address: c0000000022d6098  type: "gdb_readmem_callback"
-  crash: page excluded: kernel virtual address: c0000000022d6098  type: "gdb_readmem_callback"
-  ...
-  crash>
-
-And this issue can not be reproduced on crash 8, which only occurred
-after the gdb-16.2 upgrade(see commit dfb2bb55e530).
-
-So far I haven't found out why it always reads the same address(excluded
-page) many times, anyway, crash tool should avoid flooding messages firstly,
-similarly let's use the same debug level(8) such as the read_diskdump()(see
-diskdump.c).

+Subject: [PATCH 02/14] Fix typos in offset_table and missing "help -o" items
+
+A few of zram related members in the offset_table have typos and
+irregular naming rule, also they are not present in the "help -o"
+output.  Let's fix these.

+Subject: [PATCH 03/14] zram: Fixes for lookup_swap_cache()
+
+Fix the following three issues:
+(1) swap cache missing page tree offset
+    The radix or xarray start at an offset inside struct address_space.
+(2) swap cache entries are pointer to struct page
+    The entries in radix, xarray (swap cache) are address to struct page.
+(3) exclude shadow entries from swap cache lookup
+    radix or xarray can contain shadow entries from previous page
+    entries. These should be ignored when looking for a page pointer.
+
+Without the patch,
+- lookup_swap_cache() returns NULL since do_xarray() call returns FALSE,
+- in try_zram_decompress(), since 'entry' is NULL, page is filled with 0,
+    if (!entry || (flags & ZRAM_FLAG_SAME_BIT)) {
+and pages in swap cache will be seen to be a 'zero' page.

+The root cause is, after kernel module been loaded by mod command, the symtable
+is not expanded in gdb side. crash bt or dis command will trigger such an
+expansion. However the symtable expansion is different for the 2 commands:

+  #27 0x00000000005ab1cb in cmd_bt ...
+
+For the stacktrace of "dis -rl", it calls dw2_expand_all_symtabs() to expand
+all symtable of the objfile, or "*.ko.debug" in our case. However for
+the stacktrace of "bt", it doesn't expand all, but only a subset of symtable
+which is enough to find a symbol by dw2_lookup_symbol(). As a result, the
+objfile->compunit_symtabs, which is the head of a single linked list of
+struct compunit_symtab, is not NULL but didn't contain all symtables. It
+will not be reinitialized in gdb_get_line_number() by "dis -rl" because
+!objfile_has_full_symbols(objfile) check will fail, so it cannot display
+the proper code line number data.
+
+Since objfile_has_full_symbols(objfile) check cannot ensure all symbols
+been expanded, this patch add a new member as a flag for struct objfile
+to record if all symbols have been expanded. The flag will be set only ofter
+expand_all_symtabs been called.

+Subject: [PATCH 05/14] symbols: skip load .init.* sections if module was
+ successfully initialized
+
+There might be address overlap of one modules .init.text symbols and
+another modules .text symbols. As a result, gdb fails to translate the
+address to symbol name correctly:
+
+  crash> sym -m virtio_blk | grep MODULE
+  ffffffffc00a4000 MODULE START: virtio_blk
+  ffffffffc00a86ec MODULE END: virtio_blk
+  crash> gdb info address floppy_module_init
+  Symbol "floppy_module_init" is a function at address 0xffffffffc00a4131.
+
+Since the .init.* sections of a module had been freed by kernel if the
+module was initialized successfully, there is no need to load the .init.*
+sections data from "*.ko.debug" in gdb to create such an overlap.
+lm->mod_init_module_ptr is used as a flag of whether module is freed.
+
+Without the patch:
+  crash> mod -S
+  crash> struct blk_mq_ops 0xffffffffc00a7160
+  struct blk_mq_ops {
+    queue_rq = 0xffffffffc00a45b0 <floppy_module_init+1151>, <-- translated from module floppy
+    map_queue = 0xffffffff813015c0 <blk_mq_map_queue>,
+    ...snip...

+    init_request = 0xffffffffc00a4260 <floppy_module_init+303>,
+    ...snip...
+  }
+

+
+Then the variable 'nr_swapper_spaces' is not read (unless

+out. But the same change provided a new way to obtain the same

+Subject: [PATCH 11/14] RISCV64: Fix 'bt' output when no ra on the stack top
+
+Same as the Linux commit f766f77a74f5 ("riscv/stacktrace: Fix
+stack output without ra on the stack top").
+
+When a function doesn't have a callee, then it will not
+push ra into the stack, such as lkdtm functions, so
+correct the FP of the second frame and use pt_regs to get
+the right PC of the second frame.
+
+Before this patch, the `bt -f` outputs only the first frame with
+the wrong PC and FP of next frame:
+```
+crash> bt -f
+PID: 1        TASK: ff600000000e0000  CPU: 1    COMMAND: "sh"
+ #0 [ff20000000013cf0] lkdtm_EXCEPTION at ffffffff805303c0
+    [PC: ffffffff805303c0 RA: ff20000000013d10 SP: ff20000000013cf0 SIZE: 16] <- wrong next PC
+    ff20000000013cf0: 0000000000000001 ff20000000013d10 <- next FP
+    ff20000000013d00: ff20000000013d40
+crash>
+```
+After this patch, the `bt` outputs the full frames:
+```
+crash> bt
+PID: 1        TASK: ff600000000e0000  CPU: 1    COMMAND: "sh"

+In addition, those symbols required by the -l option were for very old
