[PATCH] Btrfs: protect orphan block rsv with spin_lock
...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.

[RFC PATCH] Btrfs: fix memory leak of orphan block rsv
...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...

Page fault on mapped pages with reserved bits set
...try.S (XEN) Domain 33 (vcpu#0) crashed on cpu#0: The mapping corresponds with what was setup, other than the user and reserved bits being set for the L1 entry. Since this is x86-64, I understand that Xen has set the user bit for my guest kernel, but according to my paging extensions overview, the RSV bit may trigger a page fault: If set (RSV=1), may cause a page fault. 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. If the entry is not in...
