+Subject: [PATCH] Remove outdated musl hack in rlimit_nofile_safe
+
+This was incorrect, because RLIM_FMT is not the format specifier for uintmax_t.
+
+Since 53e84063a ("Change RLIM_FMT to '%llu' for non-glibc builds (#269)"),
+RLIM_FMT is correct for musl, so there's no longer any need for this casting
+version.
