jfs: Update jfs_error
Use a more current logging style. Add __printf format and argument verification. Remove embedded function names from formats. Add %pf, __builtin_return_address(0) to jfs_error. Add newlines to formats for kernel style consistency. (One format already had an erroneous newline) Coalesce formats and align arguments. Object size reduced ~1KiB. $ size fs/jfs/built-in.o* text data bss dec hex filename 201891 35488 63936 301315 49903 fs/jfs/built-in.o.new 202821 35488 64192 302501 49da5 fs/jfs/built-in.o.old Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
