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/alp= ha with the additional parameter.
