Description Michael S. Tsirkin 2015-09-09 08:37:36 UTC 
I have a directory mounted with encfs:
encfs -o nonempty /home/mst/Encrypted /home/mst/Private

lockfile in this directory fails:
$ lockfile -r 1 -s 1 $HOME/Private/Calendar.ics.lock
lockfile: Try praying, giving up on "/home/mst/Private/Calendar.ics.lock"

but works fine if I run lockfile under strace:
$ strace -f -o /dev/null lockfile -r 1 -s 1 $HOME/Private/Calendar.ics.lock
$ echo $?
0

This happens every time.

Note: I'm using 32 bit userspace and 64 bit kernel.
Comment 1 Michael S. Tsirkin 2015-09-09 08:45:20 UTC 
I just reproduced this with a 32 bit kernel as well.
This is using Fedora 22.
