liburing
|
|
--------
|
|
|
|
This is the liburing library. liburing provides helpers to setup and
|
|
teardown io_uring instances, and also a simplified interface for
|
|
applications that don't need (or want) to deal with the full kernel
|
|
side implementation.
|
|
|
|
For more info on io_uring, please see:

ulimit settings
|
|
---------------
|
|
|
|
io_uring accounts memory it needs under the rlimit memlocked option, which
|
|
can be quite low on some setups (64K). The default is usually enough for
|
|
most use cases, but bigger rings or things like registered buffers deplete
|
|
it quickly. root isn't under this restriction, but regular users are. Going
|
|
into detail on how to bump the limit on various systems is beyond the scope
|
|
of this little blurb, but check /etc/security/limits.conf for user specific
|
|
settings, or /etc/systemd/user.conf and /etc/systemd/system.conf for systemd
|
|
setups.
