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.

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
