Hi,
i got stuck while selecting the right FS for ceph / RBD.
XFS:
- deadlock / hung task under 3.0.34 in xfs_ilock / xfs_buf_lock while syncfs
- under 3.5-rc3 all my machines got loaded doing nothing than waiting
for XFS / SSDs so ceph is really slow / unuseable
btrfs:
- 3.5-rc3 ceph is prett

I would but both XFS and btrfs are crashing after a short period.
XFS crashes with this one:
