Hi Alexei Starovoitov,
Have you ever read this mail?
I'm very intrerested in triggering perf sample in BPF code.
You said it is not a problem. Could you please give me some
further information?
Thank you.

Ok, saw it on lkml. Guess I need more coffee, sorry..

This looks reasonable, but I miss Ccs to the authors of the

I have created today's linux-next tree at
git://git.
The lo_ctl_mutex is held for running all ioctl handlers, and
in some ioctl handlers, ioctl_by_bdev(BLKRRPART) is called for
rereading partitions, which requires bd_mutex.
So it is easy to cause failure because trylock(bd_mutex) may
fail inside blkdev_reread_part(), and follows the lock context:

The only possible problem of using mutex_lock() instead of trylock
is about deadlock.
If there aren't any locks held before calling blkdev_reread_part(),
deadlock can't be caused by this conversion.
If there are locks held before calling blkdev_reread_part(),
and if these locks arn't required in
From: Jarod Wilson
With the mutex_trylock bit gone from blkdev_reread_part(), the retry logic
in dasd_scan_partitions() shouldn't be necessary.

loop_clr_fd() can be run piggyback with lo_release(), and
under this situation, reread partition may always fail because
bd_mutex has been held already.
This patch detects the situation by the reference count, and
call __blkdev_reread_part() to avoid acquiring the lock again.

Hi Guys,
Recently there are several reports about loop partition scanning
failure[1][2].
For loop, the root cause is one ABBA and one AA lock dependency
issue, and the two are fixed by patch 2 and patch 3 each.
Another reason is from the trylock in blkdev_reread_part(), which
may cause partition
From: Jarod Wilson
This patch exports blkdev_reread_part() for block drivers, also
introduce __blkdev_reread_part().
For some drivers, such as loop, reread of partitions can be run
from the release path, and bd_mutex may already be held prior to
calling ioctl_by_bdev(bdev, BLKRRPART, 0), so intr
