[Linux] limitのデフォルト値
shellや/etc/security/limits.confで上書きされるので最初のデフォルト値ってどうやってみれば良いのかと調べてた。
initの値を見れば良いのか。
$ cat /proc/1/limits Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size 8388608 unlimited bytes Max core file size 0 unlimited bytes Max resident set unlimited unlimited bytes Max processes 61308 61308 processes Max open files 1024 4096 files Max locked memory 65536 65536 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 61308 61308 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us
ソースコード的にはinclude/asm-generic/resource.h
