treewide: Add __GFP_NOWARN to k.alloc calls with v.alloc fallbacks

2013-08-20T11:06:40Z

Don't emit OOM warnings when k.alloc calls fail when there there is a v.alloc immediately afterwards. Converted a kmalloc/vmalloc with memset to kzalloc/vzalloc. Signed-off-by: Joe Perches Acked-by: "Theodore Ts'o" Signed-off-by: Jiri Kosina

drbd: Allow online change of al-stripes and al-stripe-size

2013-06-28T14:04:36Z

Allow to change the AL layout with an resize operation. For that the reisze command gets two new fields: al_stripes and al_stripe_size. In order to make the operation crash save: 1) Lock out all IO and MD-IO 2) Write the super block with MDF_PRIMARY_IND clear 3) write the bitmap to the new location (all zeros, since we allow only while connected) 4) Initialize the new AL-area 5) Write the super block with the restored MDF_PRIMARY_IND. 6) Unfreeze all IO Since the AL-layout has no influence on the protocol, this operation needs to be beforemed on both sides of a resource (if intended).

drbd: Ignore the exit code of a fence-peer handler if it returns too late

2013-06-28T14:04:36Z

In case the connection was established and lost again before the a fence-peer handler returns, ignore the exit code of this instance. (And use the exit code of the later started instance) Signed-off-by: Andreas Gruenbacher Signed-off-by: Philipp Reisner Signed-off-by: Jens Axboe

block_device_operations->release() should return void

The value passed is 0 in all but "it can never happen" cases (and those only in a couple of drivers) *and* it would've been lost on the way out anyway, even if something tried to pass something meaningful. Just don't bother. Signed-off-by: Al Viro
