vfs_io_uring — Implement async io in Samba vfs using io_uring of Linux (>= 5.1).
vfs objects = io_uring
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.
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'.
Use the IORING_SETUP_SQPOLL feature.
The default is 'no'.
