+Subject: [PATCH] core: set fs.file-max sysctl to LONG_MAX rather than
+ ULONG_MAX
+
+Since kernel 5.2 the kernel thankfully returns proper errors when we
+write a value out of range to the sysctl. Which however breaks writing
+ULONG_MAX to request the maximum value. Hence let's write the new
+maximum value instead, LONG_MAX.
