2.4.14-pre3 and umount

2.4.14-pre3 and umount

[Ed Tomlinson]

Hi,

I am running 2.4.14-pre3 patched with LVM 1.01rc4 and the vfs locking patch
for 2.4.11 and above.  I performed the following actions after which umount
fails.

mount /back
cd /back
ran a backup which filled the reiserfs on lvm /back fs.
cd ..
umount /back

and the umount tells me /back is busy.  Why? Does anyone 
else see this behavior?  With straight 2.4.14-pre3?

TIA,
Ed Tomlinson (off to sleep now)

might have a process accessing /back?
lsof|grep back

Try this patch, which is floating around for over half a year already and 
still not in the kernel:

Forgot about lsof...  it found a gzip hiding.  I had tried
ps -eaf | grep back but found nothing.  

I am glad this turn out to be a non bug - pre3 seems to be
a quite nice kernel here.

Thanks
