...ceph. Turns out it''s because we''re racing with checking if the orphan block reserve is set, because we clear it outside of the spin_lock. So leave the normal fastpath checks where they are, but take the spin_lock and _recheck_ to make sure we haven''t had an orphan block rsv added in the meantime. Then clear the root''s orphan block rsv and release the lock. With this patch a user said the warnings went away and they usually showed up pretty soon after he started ceph.

I'm trying to get RSV-S8 working with Citrix XenServer 5 update 3 (which I believe runs CentOS 5.something). I have the Rosewill card that comes with it in there (sil3132 based). It's seeing the card, and seeing all my drives. I fdisk the drives and I can create the partitions, but I am unable to set up eithe...

We have two time series: the first is a series of weekly counts of isolates of RSV (respiratory syncytial virus) by pathology laboratories, and the second is a series of weekly counts of cases of bronchiolitis in young children presenting to hospital emergency departments. Bronchiolitis in young children is usually caused by RSV infection, and simple visual inspection reveals...

Hello, I''m seeing a lot of warnings in dmesg with a BTRFS filesystem. I''m using the 3.1 kernel, I found a patch for these warnings ( http://marc.info/?l=linux-btrfs&m=131547325515336&w=2) <http://marc.info/?l=linux-btrfs&m=131547325515336&w=2>, but that patch has already been included in 3.1. Are there any other patches I can try? I''m using

...t result in a commit, that is, inode.c:btrfs_orphan_commit_root() doesn''t get called (via transaction.c:commit_fs_roots()). The respective inode will end up being called by inode.c:btrfs_evict_node() (via the VFS). So my likely dirty hack, after some debugging, of freeing the orphan block rsv in btrfs_evict_inode() if its not being used by other tasks, seems to fix the leak without failing xfstests so far. But this is unlikely to be a correct solution without causing issues elsewhere. This commit also changes calls to btrfs_orphan_del() which grabbed the root''s orphan_block_rs...

Setting this bit only causes a page fault during page translation. If the referenced page entry is in the TLB, then setting this bit, and referencing the page will not cause a page fault.
