vfs_io_uring - Implement async io in Samba vfs using io_uring of Linux (>= 5.1).

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed
       by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.

Samba 4.22.3-Ubuntu-4.22.3+dfs                     07/21/2025                                    VFS_IO_URING(8)

       This VFS module is part of the samba(7) suite.

       The io_uring VFS module enables asynchronous pread, pwrite and fsync using the io_uring infrastructure of
       Linux (>= 5.1). This provides much less overhead compared to the usage of the pthreadpool for async io.

       This module SHOULD be listed last in any module stack as it requires real kernel file descriptors.

       Straight forward use:

       io_uring:num_entries = NUMBER_OF_QUEUE_ENTRIES
           The number of entries in the submission queue. The maximum allowed value depends on the kernel
           version and the kernel will roundup the value to a power of 2.

           The default is '128'.

       io_uring:sqpoll = BOOL
           Use the IORING_SETUP_SQPOLL feature.

           The default is 'no'.
