Subject: [PATCH] udev: raise RLIMIT_NOFILE as high as we can
|
||
|
|
|
||
|
|
We might need a lot of fds on large systems, hence raise RLIMIT_NOFILE
|
||
|
|
to what the service manager allows us, which is quite a lot these days.
|
||
|
|
|
||
|
|
udev already sets FORK_RLIMIT_NOFILE_SAFE when forking of chilren, thus
|
||
|
|
ensuring that forked off processes get their RLIMIT_NOFILE soft limit
|
||
|
|
reset to 1K for compat with crappy old select().
|
||
|
|
|
||
|
|
Replaces: #29298
|
||
|
|
Fixes: #28583

||
