ext4: fix transposition typo in format string
According to C99, %*.s means the same as %*.0s, in other words, print as many spaces as the field width argument says and effectively ignore the string argument. That is certainly not what was meant here. The kernel's printf implementation, however, treats it as if the . was not there, i.e. as %*s. I don't know if de->name is nul-terminated or not, but in any case I'm guessing the intention was to use de->name_len as precision instead of field width. [ Note: this is debugging code which is commented out, so this is not security issue; a developer would have to explicitly enable INLINE_DIR_DEBUG before this would be an issue. ] Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
