| |
Hello!
There seems to be some confusion going on among the users who try to use non-standard blocksize reiserfs filesystems with 2.4 kernels (where this support is not yet merged) and are able to easily crash kernel this way, so it seems following patch is necessary for now, that only allows to mount 4K-blocksize reiserfs filesystems.
Please apply.
Thank you.
Bye, Oleg
