Subject: [PATCH] Fix mdflush on RHEL9
|
||||
|
||||
Since kernel commit 309dca309fc ("block: store a block_device pointer
|
||||
in struct bio") struct bio points again to a block_device and not to a
|
||||
gendisk directly. However mdflush is looking at the presence or not of
|
||||
the bio_dev macro to check whether to get the gendisk directly from
|
||||
the bio or not, which doesn't work anymore since the bio_dev macro
|
||||
still exists. Since we don't have to deal other ekrnel kernel version
|
||||
but our own, just use the definition that we use in our kernels.

Subject: [PATCH] Handle renaming of task_struct_>state field on RHEL 9
|
||||
|
||||
There has been some cleanup of task_struct's state field and to catch
|
||||
any place that has been missed in the conversion, it has been renamed
|
||||
__state.

Subject: [PATCH] threadsnoop: look for pthread_create in libc too
|
||||
|
||||
Since glibc 2.34, pthread features are integrated in libc directly.
|
||||
Look for pthread_create there too when it is not found in libpthread.
|
||||
|
||||
Fixes #3623

Subject: [PATCH] tools/readahead compatible with kernel version >= 5.10
|
||||
(#3507)
|
||||
|
||||
After kernel version 5.10, __do_page_cache_readahead() was renamed to do_page_cache_ra(),
|
||||
let us try both in readahead.py.
