[PATCH] strtok --> strsep in filesystem drivers (part 1)

Fri, 16 Nov 2001 21:31:32 +0100


Hello again,

patch below is for making most of the filesystem drivers strtok()-free.
Part 2 will consist of some not so boring chunks.

As usual, the patch is untested. It survived a heavy staring-at-it,
though. ;) Please, apply.

René
