They should apply cleanly, if you are worried about some offsets, this is ok and should not concern you.

Any reason for us not to use SuSE is including these into their SuSE 8.1 shipped kernels, so I guess they are tested. Probably Chris can comment more on this. > Are there any other patches we should be adding?

You may need to apply 05-reiserfs_make_bad_inode.diff from 2.4.19.pending subdir on our FTP, if you are going to use NFS off reiserfs. Bye, Oleg
