The new back reference format does not allow reusing objectid of deleted snapshot/subvol. So we use ++highest_objectid to allocate objectid for new snapshot/subvol. Now we use ++highest_objectid to allocate objectid for both new inode and new snapshot/subvolume, so this patch removes 'find hole' code in btrfs_find_free_objectid.

A small warning popped up on ia64 because inode-map.c was comparing a u64 object id with the ULL FIRST_FREE_OBJECTID. My first thought was that all the OBJECTID constants should contain the u64 cast because btrfs code deals entirely in u64s. But then I saw how large that was, and figured I'd just fix the max() call.

btrfs_init_path was initially used when the path objects were on the stack. Now all the work is done by btrfs_alloc_path and btrfs_init_path isn't required. This patch removes it, and just uses kmem_cache_zalloc to zero out the object. Signed-off-by: NChris Mason <chris.mason@oracle.com>

There were many, most are fixed now. struct-funcs.c generates some warnings but these are bogus. Signed-off-by: NChris Mason <chris.mason@oracle.com>

* Add an EXTENT_BOUNDARY state bit to keep the writepage code from merging data extents that are in the process of being relocated. This allows us to do accounting for them properly. * The balancing code relocates data extents indepdent of the underlying inode. The extent_map code was modified to properly account for things moving around (invalidating extent_map caches in the inode). * Don't take the drop_mutex in the create_subvol ioctl. It isn't required. * Fix walking of the ordered extent list to avoid races with sys_unlink * Change the lock ordering rules. Transaction start goes outside the drop_mutex. This allows btrfs_commit_transaction to directly drop the relocation trees. Signed-off-by: NChris Mason <chris.mason@oracle.com>

Orphan items use BTRFS_ORPHAN_OBJECTID (-5UUL) as key objectid. This affects the find free objectid functions, inode objectid can easily overflow after orphan file cleanup. --- Signed-off-by: NChris Mason <chris.mason@oracle.com>

Extent alloctions are still protected by a large alloc_mutex. Objectid allocations are covered by a objectid mutex Other btree operations are protected by a lock on individual btree nodes Signed-off-by: NChris Mason <chris.mason@oracle.com>

btrfs_find_free_objectid may return a used objectid due to arithmetic underflow. This bug may happen when parameter 'root' is tree root, so it may cause serious problems when creating snapshot or sub-volume. Signed-off-by: NChris Mason <chris.mason@oracle.com>
