Description of problem:
Making upgrade to 2.4.3-12 kernel, if I have a reiserfs partition, I
can't umount it.

How reproducible:

Steps to Reproduce:
1. Upgrade do Kernel 2.4.3-12 from RedHat Errata, boot it.
2. If you wanna, upgrade to mount-2.11b-3 too, no matters.
3. Format a partition with reiserfs (mkreiserfs /dev/XXXX)
4. Mount the partition.
5. Try Umount the partition.

Actual Results:  umount never return, don't umount.

Expected Results:  umount the partition.

Additional info:

It may cause loss of data on computer shutdown, when umount can't
umount the reiserfs, and keep other open, the only way is pressing
Reset button.

Could you try the 2.4.3-15 kernel I put on
http://people.redhat.com/arjanv/testkernels  ?
That should have a fix for this.

This bug is the same as 45628.  Should close this and mark as duplicate of 45628.

Comment 3 John Dalbec 2001-08-17 12:05:16 UTC
I tried kernel 2.4.3-15.  It worked for me.  Does this kernel include the ReiserFS/NFS compatibility patch for knfsd?

Comment 4 Arjan van de Ven 2001-08-17 12:09:06 UTC
no, that patch wasn't ready for mainstream in the 2.4.3 timeframe.

Comment 5 John Dalbec 2001-08-22 19:08:00 UTC
In 2.4.3-15, did you just enable CONFIG_REISERFS_CHECK instead of applying a
patch for umount?  Is this going to cause a big performance hit?

Comment 6 Arjan van de Ven 2001-08-22 20:37:38 UTC
I didn't touch that setting in -15; just fixed the real bug.
There now is a -16 up (same place) with a fix for the dmfe NIC driver; if/when I
make a -17 I can disable this check; however Chris Mason (SuSE, major reiserfs
contributor) doesn't think it makes a lot of performance difference, except in
strange benchmark cornercases.
