Subject: [PATCHSET 0/4] Allow relative lookups
Date: Fri,  7 Feb 2020 08:50:35 -0700
Message-ID: <> (raw)

Due to an oversight on my part, AT_FDCWD lookups only work when the
lookup can be done inline, not async. This patchset rectifies that,
aiming for 5.6 for this one as it would be a shame to have openat etc
without that.

Just 3 small simple patches - grab the task ->fs, add io-wq suppor for
passing it in and setting it, and finally add a ->needs_fs to the opcode
table list of requirements for openat/openat2/statx.

Last patch just ensures we allow AT_FDCWD.

 fs/io-wq.c    | 19 +++++++++++++++----
 fs/io-wq.h    |  4 +++-
 fs/io_uring.c | 29 ++++++++++++++++++++++++++++-
