Bug 194231 – umount -art afs" hangs when inotify is compiled into the kernel

• Product: Gentoo Linux
• Status: VERIFIED NEEDINFO

[Description Anton Firsov 2007-09-29 23:05:01 UTC]

The command "umount -art afs" hangs, when inotify is compiled to the kernel
(CONFIG_INOTIFY=y)

My kernel version:
gentoo sources 2.6.22-r2

When I recompiled my kernel without inotify (# CONFIG_INOTIFY is not set), the problem disappeared.


Reproducible: Always

Steps to Reproduce:
umount -art afs
Actual Results:  
I checked this command with strace. (strace umount -art afs)
The last line was:
sync(

Expected Results:  
Do nothing, because I do not use afs!

Actually I do not use afs, the script /etc/init.d/netmount, "generates" the following command:
"umount -art afs,cifs,coda,davfs,fuse,gfs,ncpfs,nfs,nfs4,ocfs2,shfs,smbfs"

Please try w/ 2.13-r1

[Comment 4 Anton Firsov 2007-10-03 21:51:10 UTC]

I was wrong in my first report. I had the kernel 2.6.19 (as the emerge info shows).
With kernel 2.6.22-gentoo-r2 the problem disappears!

I tried util-linux 2.13-r1, but with the kernel 2.6.19, umount still does not work.

Well, so upgrade your kernel.
