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. |
