V3:
- fix one crash bug in the first patch.
V2:
- minor fixes to clean up the code from Jeff's comments, thanks
- swith to use lockdep_assert_held().
Test this for around 5 hours and this patch series worked well for me, my test script is:
$ while [ 1 ]; do date; for d in A B C; do (for i in {1..3}; do ./bin/mount.ceph :/ /mnt/kcephfs.$d -o noshare; rm -rf /mnt/kcephfs.$d/file$i.txt; rmdir /mnt/kcephfs.$d/.snap/snap$i; dd if=/dev/zero of=/mnt/kcephfs.$d/file$i.txt bs=1M count=8; mkdir -p /mnt/kcephfs.$d/.snap/snap$i; umount -fl /mnt/kcephfs.$d; done ) & done; wait; date; done
