Subject: [PATCH 0/2] io_uring: fix locking in __io_run_local_work
Date: Thu, 27 Oct 2022 07:44:27 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
If locked was not set in __io_run_local_work, but some task work managed
to lock the context, it would leave things locked indefinitely. Fix that
by passing the pointer in.
Patch 1 is a tiny cleanup to simplify things
Patch 2 is the fix
Dylan Yudaken (2):
io_uring: use io_run_local_work_locked helper
io_uring: unlock if __io_run_local_work locked inside
