+Subject: fs/fat: strip "cp" prefix from codepage in display
+X-Git-Tag: next-20121130~1^2~97
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fnext%2Flinux-next.git;a=commitdiff_plain;h=f15914873184cc3f2a8d590fa4f7e32ab0a8a405

+fs/fat: strip "cp" prefix from codepage in display
+
+Option parsing code expects an unsigned integer for the codepage option,
+but prefixes and stores this option with "cp" before passing to
+load_nls().  This makes the displayed option in /proc an invalid one.
+Strip the prefix when printing so that the displayed option is valid for
+reuse.
