ceph: use ihold when we already have an inode ref

2011-06-08T04:34:11Z

We should use ihold whenever we already have a stable inode ref, even when we aren't holding i_lock. This avoids adding new and unnecessary locking dependencies. Signed-off-by: Sage Weil

ceph: do not use i_wrbuffer_ref as refcount for Fb cap

2011-05-11T17:44:48Z

We increments i_wrbuffer_ref when taking the Fb cap. This breaks the dirty page accounting and causes looping in __ceph_do_pending_vmtruncate, and ceph client hangs. This bug can be reproduced occasionally by running blogbench. Add a new field i_wb_ref to inode and dedicate it to Fb reference counting. Signed-off-by: Henry C Chang Signed-off-by: Sage Weil

ceph: do not call __mark_dirty_inode under i_lock

2011-05-04T19:56:45Z

The __mark_dirty_inode helper now takes i_lock as of 250df6ed. Fix the one ceph callers that held i_lock (__ceph_mark_dirty_caps) to return the flags value so that the callers can do it outside of i_lock. Signed-off-by: Sage Weil

ceph: add ino32 mount option

2011-03-21T19:24:22Z

The ino32 mount option forces the ceph fs to report 32 bit ino values. This is useful for 64 bit kernels with 32 bit userspace. Signed-off-by: Yehuda Sadeh

ceph: preserve I_COMPLETE across rename

2011-03-15T16:14:03Z

d_move puts the renamed dentry at the end of d_subdirs, screwing with our cached dentry directory offsets. We were just clearing I_COMPLETE to avoid any possibility of trouble. However, assigning the renamed dentry an offset at the end of the directory (to match it's new d_subdirs position) is sufficient to maintain correct behavior and hold onto I_COMPLETE. This is especially important for workloads like rsync, which renames files into place. Before, we would lose I_COMPLETE and do MDS lookups for each file. With this patch we only talk to the MDS on create and rename. Signed-off-by: Sage Weil

ceph: do not set I_COMPLETE

2011-03-03T18:09:51Z

Do not set the I_COMPLETE flag on directories until we resolve races with dcache pruning. Signed-off-by: Sage Weil

ceph: fix getattr on directory when using norbytes

2011-01-13T23:50:06Z

The norbytes mount option was broken, and when doing getattr on a directory it return the rbytes instead of the number of entities. This commit fixes it. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: implement DIRLAYOUTHASH feature to get dir layout from MDS

2011-01-12T23:15:13Z

This implements the DIRLAYOUTHASH protocol feature, which passes the dir layout over the wire from the MDS. This gives the client knowledge of the correct hash function to use for mapping dentries among dir fragments. Note that if this feature is _not_ present on the client but is on the MDS, the client may misdirect requests. This will result in a forward and degrade performance. It may also result in inaccurate NFS filehandle generation, which will prevent fh resolution when the inode is not present in the client cache and the parent directories have been fragmented.
