rgw: Fallback to Host header for bucket name.
RGW should fallback to using the Host header as the bucket name if valid &
possible even when it is NOT a suffix match against the DNS names, or a match
against the CNAME rule.
This mirrors AWS S3 behavior for these cases (The AWS S3 does not do any DNS
lookups regardless).

ceph_volume_client: modify locking of meta files
File locks are applied on meta files before updating the meta

after lock was acquired on it.

ceph_volume_client: modify data layout in meta files
Notable changes to data layout in auth meta and volume meta files:
In the auth meta files, add a 'dirty' flag to track the status of auth
updates to a single volume.
In the volume meta file, make the 'dirty' flag track the status of
auth updates for a single ID.
Optimize the recovery of partial auth update changes to auth meta,
volume meta, and the Ceph backend, facilitated by changes in the
data layout in the meta files.
Store a two-way mapping between auth IDs and volumes.
Enables us to record some metadata on auth ids (which
openstack tenant created it) so that we can avoid exposing
keys to other tenants who try to use the same ceph
auth id.
Enables us to expose the list of which auth ids have access
to a volume, so that Manila's update_access() can be
implemented efficiently.

also, RGWDataSyncShardCR::stop_spawned_services() was dropping the last

ceph-disk: partprobe should block udev induced BLKRRPART
Wrap partprobe with flock to stop udev from issuing BLKRRPART because
this is racy and frequently fails with a message like:
Error: Error informing the kernel about modifications to partition
/dev/vdc1 -- Device or resource busy. This means Linux won't know about
any changes you made to /dev/vdc1 until you reboot -- so you shouldn't
mount it or use it in any way before rebooting.
Opening a device (/dev/vdc for instance) in write mode indirectly
triggers a BLKRRPART ioctl from udev (starting version 214 and up)
when the device is closed (see below for the udev release note).
However, if udev fails to acquire an exclusive lock (with
flock(fd, LOCK_EX|LOCK_NB); ) the BLKRRPART ioctl is not issued.
Acquiring an exclusive lock before running the process that opens the
device in write mode is therefore an effective way to control this
behavior.
git clone git://anonscm.debian.org/pkg-systemd/systemd.git
systemd/NEWS:
CHANGES WITH 214:
* As an experimental feature, udev now tries to lock the
disk device node (flock(LOCK_SH|LOCK_NB)) while it
executes events for the disk or any of its partitions.
Applications like partitioning programs can lock the
disk device node (flock(LOCK_EX)) and claim temporary
device ownership that way; udev will entirely skip all event
handling for this disk and its partitions. If the disk
was opened for writing, the close will trigger a partition
table rescan in udev's "watch" facility, and if needed
synthesize "change" events for the disk and all its partitions.
This is now unconditionally enabled, and if it turns out to
cause major problems, we might turn it on only for specific
devices, or might need to disable it entirely. Device Mapper
devices are excluded from this logic.

mds: handle partly purged directory
For a snapshoted direcotry whose snaprealm parents are being opened,
MDS does not know if the directory is purgeable. So MDS can't skip
committing dirfrags of the directory. But if the direcotry is purgeale,
some dirfrags could have already been deleted during MDS failover.
Committing them could return -ENOENT.
