The intent is to provide a more complete I/O interface for io_uring. Patch 1: fs: add parameter use_fpos to iterate_dir() This adds a new parameter to the function iterate_dir() so the caller can specify if the position is the file position or the position stored in the buffer context. 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. Signed-off-by: Stefan Roesch --- V2: Updated the iterate_dir calls in fs/ksmbd, fs/ecryptfs and arch/alpha with the additional parameter.
