SubjectExt2-fs error
Date
The EXT2-fs errors I recently reported for test11 seem to be gone with
test12-pre5. At least I couldn't reproduce the error, neither with
overcommit_memory turned on nor off; maybe the error was due to
turning on write cache of my hard disk.

The error was a wrong reading of directory lengths and inode nnumbers:
The file system seemed to read the inode numbers not as supposed to do:
xxxx|xxxx|xxxx|xxxx|xxxx
rrrr

but like this:
xxxx|xxxx|xxxx|xxxx|xxxx
rrr_r
The message was:
