Subject: [PATCH] biolatpcts: Build fixes on recent kernels
|
||||
|
||||
* `struct request` definition recently moved from blkdev.h to blk-mq.h
|
||||
breaking both tools/biolatpcts and examples/tracing/biolatpcts. Fix them
|
||||
by also including blk-mq.h.
|
||||
|
||||
* blk_account_io_done() got split into two parts - inline condition checks
|
||||
and the actual accounting with the latter now done in
|
||||
__blk_account_io_done(). The kprobe attachment needs to be conditionalized
|
||||
to work across the change. tools/biolatpcts was already updated but
|
||||
examples/tracing/biolatpcts wasn't. Fix it.

Subject: [PATCH] tools: Fix BCC bio tools with recent kernel change
|
||||
|
||||
Several BCC bio tools are broken due to kernel change ([0]).
|
||||
blk_account_io_{start, done} were renamed to __blk_account_io_{start, done},
|
||||
and the symbols gone from /proc/kallsyms. Fix them by checking symbol existence.

Subject: [PATCH] tools: include blk-mq.h in bio tools
|
||||
|
||||
Kernel commit 24b83deb29b ("block: move struct request to blk-mq.h")
|
||||
has moved struct request from blkdev.h to blk-mq.h. It results in
|
||||
several bio tools to fail with errors of the following type:
|
||||
|
||||
error: incomplete definition of type 'struct request'
|
||||
|
||||
Since blk-mq.h had always included blkdev.h. it is safe to simply
|
||||
replace the inclusion of blkdev.h by blk-mq-h. It works on both older
|
||||
and newer kernel.
|
||||
|
||||
Fixes: #3869
