[PATCH] strtok --> strsep in filesystem drivers

From: René Scharfe (l.s.r@web.de)
Date: Wed Oct 24 2001 - 18:02:51 EST


Hi,

here comes another strtok related patch. This time all strtok calls in
filesystem drivers are converted to strsep calls.

This patch is made against kernel 2.4.13 and applies, with some
offsets, against kernel 2.4.12-ac6, too.

As usual, I did NOT test this patch. ;) It compiles, though. Please
apply.

René
