[PATCH 0/2] isofs: tie the name conversion buffer to its bound

[Matthias Goergens <matthias.goergens@gmail.com>]

Two cleanups around the scratch buffer isofs_readdir() and
isofs_lookup() hand to the name converters.  No functional change; the
first patch's assertions hold on the current code.

Found while looking at something else: get_joliet_filename() has been
passing PAGE_SIZE as its output bound since b2eb2e288604 shrank the
buffer to 1024, which is safe only because de->name_len is a single
byte.  That seemed worth writing down in a form the compiler checks.

Matthias Goergens (2):
  isofs: size the name conversion buffer from a named constant
  isofs: bound the Joliet iocharset conversion by the output buffer
