Subject: [PATCH] RHEL/Centos: tools: fix alignment in tp_args for bio tools
|
||||
|
||||
The padding in tp_args is wrong on RHEL 9 / c9s kernel because of the
|
||||
kernel commit 6bc27040eb90 ("sched: Add support for lazy preemption")
|
||||
which added a common field to tracepoints.
|
||||
|
||||
Now the dev field is at an offset of 12 bytes as shown by
|
||||
block_io_start/done format file.

||||
