[PATCH] hpfs: bring hpfs_error() into shape
- switch to error message buffer in .bss - missing va_end() (htf it worked before?) - use vsnprintf() - rename variables to understandable "fmt", "args". - "const char *fmt", yes. - add __attribute__((format ... Still, put that coffee down before reading more. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
