Another new disk format pushed to -unstable
Hello everyone,
btrfs-unstable now has Yan Zheng''s fallocate support, along with disk
format changes.
I was hoping to roll all of this into a single format change with the
compression code, but there was too much conflict between the two
patches.
The fallocate work is pretty neat, it allows preallocation of extents
and overwrites them without triggering COW as long as there are no

New new format branch ready for testing
Hello everyone,
Yan Zheng sent along an update for the new format patch today, and it
slightly changed the disk format for backrefs used when balancing space
across drives. We decided against supporting an intermediate format
that was only a week old, and his update makes a few important features
much much easier (snapshot deletion for one).

[Patch v2] btrfs: use file_remove_suid() after i_mutex is held
V1 -> V2:
Move kmalloc() before mutex_lock(), suggested by Arjan.
file_remove_suid() should be called with i_mutex held,
file_update_time() too. So move them after mutex_lock().
Plus, check the return value of kmalloc().

[PATCH] Progs: update convert for uninitialized block groups
Hello,
There is a new feature ''uninitialized block groups'' in ext4.
Block and inode bitmaps in uninitialized block groups are
uninitialized. This confuses the converter. The fix is call
ext2fs_new_inode for each block group at open time. It set
up uninitialized block and inode bitmaps appropriately.
This patch also contains some other minor fixes. Thank you,

system hang with btrfs master
I''m using btrfs on two devices here, /usr on sda3 and /home on sdb (dm-crypt

snapshot/subvol deletion
Hi,
I will send a series patches that add snapshot/subvol deletion soon.
But the way to delete snapshot/subvol is far from people''s expectancy.
To delete a snapshot/subvol, we need four steps: 1) snapshot/subvol
deletion ioctl or rmdir; 2) umount; 3) btrfsck; 4) mount the fs.
The reason for this is bug in root back & forward references. In simple
terms, the bug prevents us from

We do log replay in a single transaction, so it''s not good to

orphan inodes cleanup executed after replaying log. It also
avoid doing other unbound operations such as truncating a file
during replaying log. These unbound operations are postponed
to the orphan inode cleanup stage.

This patch contains two changes to avoid unnecessary tree block reads during
snapshot dropping. First, check tree block''s reference count and flags before
reading the tree block. if reference count > 1 and there is no need to update
backrefs, we can avoid reading the tree block. Second, save when snapshot was
created in root_key.offset. we can compare block pointer''s

[PATCH] Btrfs: make sure we find a bitmap entry
Yan Zheng hit a problem where we tried to remove some free space but failed
because we couldn''t find the free space entry. This is because the free space
was held within a bitmap that had a starting offset well before the actual
offset of the free space, and there were free space extents that were in the
same range as that offset, so tree_search_offset returned with NULL because we
