vfs_io_uring
Implement async io in Samba vfs using io_uring of Linux (>= 5.1).
vfs objects = io_uring
DESCRIPTION
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.
EXAMPLES
Straight forward use:
/data/ice
io_uring
OPTIONS
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'.

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.
