| |
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
