Subject: [PATCH v5 00/10] io_uring: add mkdir, [sym]linkat and mknodat support
Date: Thu, 3 Jun 2021 12:18:26 +0700 [thread overview]
Message-ID: <[email protected]> (raw)
This started out as an attempt to add mkdirat support to io_uring which
is heavily based on renameat() / unlinkat() support.
During the review process more operations were added (linkat, symlinkat,
mknodat) mainly to keep things uniform internally (in namei.c), and
with things changed in namei.c adding support for these operations to
io_uring is trivial, so that was done too. See
https://lore.kernel.org/io-uring/20210514145259.wtl4xcsp52woi6ab@wittgenstein/
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.
3-6 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.
7 changes do_* helpers in namei.c to return ints rather than some of
them returning ints and some longs.
8-10 add symlinkat, linkat and mknodat support to io_uring
(correspondingly).
Based on for-5.14/io_uring.
v5:
- rebase
- add symlinkat, linkat and mknodat support to io_uring
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 (10):
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
fs: update do_*() helpers to return ints
io_uring: add support for IORING_OP_SYMLINKAT
io_uring: add support for IORING_OP_LINKAT
io_uring: add support for IORING_OP_MKNODAT
