Subject: [PATCH v4 0/6] io_uring: add mkdirat support
Date: Thu, 13 May 2021 18:06:06 +0700	[thread overview]
Message-ID: <[email protected]> (raw)

This adds mkdirat support to io_uring and is heavily based on recently
added renameat() / unlinkat() support.

The first patch is preparation with no functional changes, makes
do_mkdirat accept struct filename pointer rather than the user string.

The second one leverages that to implement mkdirat in io_uring.

The rest of the patches just convert other similar do_* functions in
namei.c to accept struct filename, for uniformity with do_mkdirat,
do_renameat and do_unlinkat. No functional changes there.

Based on io_uring-5.13.

v4:
- update do_mknodat, do_symlinkat and do_linkat to accept struct
  filename for uniformity with do_mkdirat, do_renameat and do_unlinkat;

v3:
- rebase;

v2:
- do not mess with struct filename's refcount in do_mkdirat, instead add
  and use __filename_create() that does not drop the name on success;

Dmitry Kadashev (6):
  fs: make do_mkdirat() take struct filename
  io_uring: add support for IORING_OP_MKDIRAT
  fs: make do_mknodat() take struct filename
  fs: make do_symlinkat() take struct filename
  namei: add getname_uflags()
  fs: make do_linkat() take struct filename
