[PATCH 03/16] blkfront: don't access freed struct xenbus_device
From: Jan Beulich <jbeulich(a)novell.com> Unfortunately commit "blkfront: fixes for 'xm block-detach ... --force'" still wasn't quite right - there was a reference to freed memory left from blkfront_closing().

[PATCH 01/16] xen: use less generic names in blkfront driver.
From: Ian Campbell <ian.campbell(a)citrix.com> All Xen frontend drivers have a couple of identically named functions which makes figuring out which device went wrong from a stacktrace harder than it needs to be. Rename them to something specificto the device type. Signed-off-by: Ian Campbell <ian.campbell(a)citrix.... 20 Jul 2010 16:52

[PATCH 14/16] blkfront: Lock blockfront_info during xbdev removal
From: Daniel Stodden <daniel.stodden(a)citrix.com> Same approach as blkfront_closing: * Grab the bdev safely, holding the info mutex. * Zap xbdev safely, holding the info mutex. * Try bdev removal safely, holding bd_mutex.

[PATCH 13/16] blkfront: Fix blkfront backend switch race (bdev release)
From: Daniel Stodden <daniel.stodden(a)citrix.com> We cannot read backend state within bdev operations, because it risks grabbing the state change before xenbus gets to do it. Fixed by tracking deferral with a frontend switch to Closing. State exposure isn't strictly necessary, but the backends won't mind. For... 20 Jul 2010 16:52

[PATCH 2/7] fscache: convert operation to use workqueue instead of slow-work
Make fscache operation to use only workqueue instead of combination of workqueue and slow-work. FSCACHE_OP_SLOW is dropped and FSCACHE_OP_FAST is renamed to FSCACHE_OP_ASYNC and uses newly added fscache_op_wq workqueue to execute op->processor(). fscache_operation_init_slow() is dropped and fscache_operation_init(... 20 Jul 2010 16:52
