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: add offset parameter to iterate_dir function.
This adds an offset parameter to the iterate_dir()
function. The new parameter allows the caller to specify
the offset to use.
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
io_uring.
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.
V7: - add loff_t *parameter to iterate_dir function
- remove do_iterate_dir function
- change callers of iterate_dir function
v6: - rebased patch series
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.
