Subject: ext3 warnings from LTP rename14

Hello,

I ran the ltp-full-20070930 tests on 2.6.23-rc9-mph4 (sparc32 SMP), and am
seeing the following warnings:

EXT3-fs warning (device sdb5): ext3_rename: Deleting old file (215845), 2, error=-2
EXT3-fs warning (device sdb5): ext3_rename: Deleting old file (215845), 2, error=-2

EXT3-fs warning (device sdb5): ext3_rename: Deleting old file (215845), 2, error=-2
EXT3-fs error (device sdb5): ext3_add_entry: bad entry in directory #215845: rec_len is smaller than minimal - offset=56, inode=8026488, rec_len=0, name_len=0
Aborting journal on device sdb5.
EXT3-fs error (device sdb5) in start_transaction: Readonly filesystem
Aborting journal on device sdb5.
ext3_abort called.

The first ones are triggered the rename14 test (code attached), but I cannot
reproduce the latter issue so far.
Could it be a result of the earlier warnings?

An attempt to avoid the warning is also attached. But with that I see:
EXT3-fs warning (device sdb4): ext3_unlink: Deleting nonexistent file (305412), 0

Best regards,
Martin
