[v3,0/2] io_uring: add mkdirat support

Message

Dmitry Kadashev March 30, 2021, 5:59 a.m. UTC

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.

Based on for-5.13/io_uring.

Changes since v2:
- rebase

Changes since v1:
- 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 (2):
  fs: make do_mkdirat() take struct filename
  io_uring: add support for IORING_OP_MKDIRAT
