Hello,
Having tried the 2.4.0-test9 patch of reiserfs under 2.4.0-test10 I got
the following panic (see kdb session below). I was running bonnie on it
over NFS and at the same time running tar xIf linux-2.4.0-test10.tar.bz2
locally.
Regards,
Tigran

* panic in reiserfs: _get_block_create_0 gets bh_result->b_data = NULL

Hi Hans,
Simply starting the validation phase of SPEC SFS with NFS mounted reiserfs
filesystem panics as shown in the log below. A quick look at the source
suggests that _get_block_create_0() (and therefore, more generally,
reiserfs_get_block()) was passed a buffer head bh_result with ->b_data =
NULL. So, we panic at line 256 of fs/reiserfs/inode.c when doing:
memset (bh_result->b_data, 0, inode->i_sb->s_blocksize)
Is reiserfs supposed to be highmem-aware? I assume so.
Regards,
Tigran
