NAME 🖥️ vfs_io_uring 🖥️

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

SYNOPSIS

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:

    [cooldata]
	path = /data/ice
	vfs objects = 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.

SEE ALSO

io_uring_setup(2).

VERSION

This man page is part of version 4.20.1-Debian of the Samba suite.
