Subject: [PATCH v5 0/3] io_uring: add getdents64 support
Date: Fri, 26 Nov 2021 22:03:23 -0800	[thread overview]
Message-ID: <[email protected]> (raw)

This series adds support for getdents64 in liburing. The intent is to
provide a more complete I/O interface for io_uring.

Patch 1: fs: split off do_iterate_dir from iterate_dir function
  This splits of the function do_iterate_dir() from the iterate_dir()
  function and adds a new parameter. The new parameter allows the
  caller to specify if the position is the file position or the
  position stored in the buffer context.

  The function iterate_dir() calls do_iterate_dir().

Patch 2: fs: split off vfs_getdents function from getdents64 system call
  This splits of the iterate_dir part of the syscall in its own
  dedicated function. This allows to call the function directly from
  liburing.

Patch 3: io_uring: add support for getdents64
  Adds the functions to io_uring to support getdents64.

There is also a patch series for the changes to liburing. This includes
a new test. The patch series is called "liburing: add getdents support."

The following tests have been performed:
- new liburing getdents test program has been run
- xfstests have been run
- both tests have been repeated with the kernel memory leak checker
  and no leaks have been reported.

v5: - remove old patch (v4 contained a patch file from v3)

V4: - silence compiler warnings

V3: - add do_iterate_dir() function to Patch 1
    - make iterate_dir() function call do_iterate_dir()
      This has the advantage that the function signature of iterate_dir
      does not change

V2: Updated the iterate_dir calls in fs/ksmbd, fs/ecryptfs and arch/alpha with
    the additional parameter.


Stefan Roesch (3):
  fs: split off do_iterate_dir from iterate_dir function
  fs: split off vfs_getdents function of getdents64 syscall
  io_uring: add support for getdents64
