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.
Straight forward use:
[cooldata] path = /data/ice vfs objects = io_uring
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'.
This man page is part of version 4.16.4 of the Samba suite.
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.
