Subject: [PATCH 0/3] iopoll fixes
Date: Wed, 24 Jun 2020 19:50:06 +0300
Message-ID: <> (raw)

Did more comprehensive iopoll testing and found some more problems.

[1] is from the previous series. Actually, v2 for this one, addressing
the double-reissue bug found by Jens. It maybe not as efficient, but
simple and easy to backport.

[2,3] current->mm NULL deref

Pavel Begunkov (3):
  io_uring: fix hanging iopoll in case of -EAGAIN
  io_uring: fix current->mm NULL dereference on exit
  io_uring: fix NULL-mm for linked reqs
