ceph: fix statvfs fr_size

2013-06-20T18:28:21+00:00

commit 92a49fb0f79f3300e6e50ddf56238e70678e4202 upstream.

Different versions of glibc are broken in different ways, but the short of
it is that for the time being, frsize should == bsize, and be used as the
multiple for the blocks, free, and available fields.  This mirrors what is
done for NFS.  The previous reporting of the page size for frsize meant
that newer glibc and df would report a very small value for the fs size.

Fixes http://tracker.ceph.com/issues/3793.

ceph: Move secret key parsing earlier.

2011-03-29T19:11:16+00:00

This makes the base64 logic be contained in mount option parsing,
and prepares us for replacing the homebew key management with the
kernel key retention service.

ceph: add ino32 mount option

2011-03-21T19:24:22+00:00

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.

ceph: fix cap_wanted_delay_{min,max} mount option initialization

2011-01-19T17:23:22+00:00

These were initialized to 0 instead of the default, fallout from the RBD
refactor in 3d14c5d2b6e15c21d8e5467dc62d33127c23a644.

ceph: fsc->*_wq's aren't used in memory reclaim path

2011-01-12T23:15:14+00:00

fsc->*_wq's aren't depended upon during memory reclaim.  Convert to
alloc_workqueue() w/o WQ_MEM_RECLAIM.

ceph: implement DIRLAYOUTHASH feature to get dir layout from MDS

2011-01-12T23:15:13+00:00

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.

ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28+00:00

This factors out protocol and low-level storage parts of ceph into a
separate libceph module living in net/ceph and include/linux/ceph.  This
is mostly a matter of moving files around.  However, a few key pieces
of the interface change as well:

 - ceph_client becomes ceph_fs_client and ceph_client, where the latter
   captures the mon and osd clients, and the fs_client gets the mds client
   and file system specific pieces.
 - Mount option parsing and debugfs setup is correspondingly broken into
   two pieces.
 - The mon client gets a generic handler callback for otherwise unknown
   messages (mds map, in this case).
 - The basic supported/required feature bits can be expanded (and are by
   ceph_fs_client).

No functional change, aside from some subtle error handling cases that got
cleaned up in the refactoring process.

ceph: do not ignore osd_idle_ttl mount option

2010-08-03T19:56:57+00:00

Actually apply the mount option to the mount_args struct.
