[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



v5: Address review comments from Peter on v4
Dropping Patch 3 from v3
Patch 1: fix transport type in all drivers, possible switch case converts
Patch 2: use virObject with src->drv to avoid 'initFlag' for
         remembering 'virStorageFileInit' status
Patch 3:
* change virStorageBackendGlusterCacheQuery to *Lookup
* change virStorageBackendGlusterCacheRefresh to *Release
* Avoid the global Flags
* Thread safe measure by using virCond*
Thanks Peter!

v4: Address review comments from Peter on v3
Patch 1: changes to fix test failures
         (qemuargv2xmltest, qemuxml2argvtest, qemuxml2xmltest and virstoragetest)
Patch 2: fix hung in qemuxml2argvtest
Patch 3 v3: Split this Patch to 2 parts as below
Patch 3 v4: don't free metadata used for storage driver access
Patch 4:
* update variable naming as per standards
* virStorageBackendGlusterPreopened* -> virStorageBackendGlusterCache*
Thanks Peter!

v3: Address comments by Daniel and Peter on v2
* Split the patch to 3 parts
Patch 1: change the virStorageNetHostDef type
Patch 2: optimize calls to virStorageFileInit and friends
Patch 3: add the caching for glfs
* Thanks to Daniel, this version make all the methods as thread safe
* Thanks to Peter for pointing use of virObjectLockable, this had simplified
  rest of the parts a lot.

v2: Address review comments from Peter on v1
* Rebased on latest master
* Changes to commit msg
* Introduce storage API's for Register and Unregister of volume
* During qemu process Start/Stop and snapshot create
* Check Transport and Port type
* Atomic element add/del to list and ref counting
Pending: Treating IP and FQDN belong to same host
