4 | Subject: [PATCH] core: set fs.file-max sysctl to LONG_MAX rather than | ||
5 | ULONG_MAX | ||
6 | |||
7 | Since kernel 5.2 the kernel thankfully returns proper errors when we | ||
8 | write a value out of range to the sysctl. Which however breaks writing | ||
9 | ULONG_MAX to request the maximum value. Hence let's write the new | ||
10 | maximum value instead, LONG_MAX. | ||
11 | |||
12 | /cc @brauner | ||

14 | Fixes: #12803 | ||
15 | |||
16 | Upstream-Status: Backport | ||
