Btrfs: cache extent state when writing out dirty metadata pages

2012-10-09T13:15:41+00:00

Everytime we write out dirty pages we search for an offset in the tree,
convert the bits in the state, and then when we wait we search for the
offset again and clear the bits.  So for every dirty range in the io tree we
are doing 4 rb searches, which is suboptimal.  With this patch we are only
doing 2 searches for every cycle (modulo weird things happening).  Thanks,

Btrfs: fix error handling in delete_block_group_cache()

2012-10-01T19:19:14+00:00

btrfs_iget() never return NULL.
So, NULL check is unnecessary.

Btrfs: add a new "type" field into the block reservation structure

2012-10-01T19:19:11+00:00

Sometimes we need choose the method of the reservation according to the type
of the block reservation, such as the reservation for the delayed inode update.
Now we identify the type just by comparing the address of the reservation
variants, it is very ugly if it is a temporary one because we need compare it
with all the common reservation variants. So we add a new "type" field to keep
the type the reservation variants.

btrfs: use printk_get_level and printk_skip_level, add __printf, fix fallout

2012-07-31T00:25:14+00:00

Use the generic printk_get_level() to search a message for a kern_level.

Add __printf to verify format and arguments.  Fix a few messages that
had mismatches in format and arguments.  Add #ifdef CONFIG_PRINTK blocks
to shrink the object size a bit when not using printk.

Btrfs: fix error handling in __add_reloc_root()

2012-07-23T20:27:53+00:00

We dereferenced "node" in the error message after freeing it.  Also
btrfs_panic() can return so we should return an error code instead of
continuing.

Btrfs: Prevent root_list corruption

2012-04-27T17:55:13+00:00

I was seeing root_list corruption on unmount during fs resize in 3.4-rc4; add
correct locking to address this.

btrfs: replace many BUG_ONs with proper error handling

2012-03-22T10:52:54+00:00

 btrfs currently handles most errors with BUG_ON. This patch is a work-in-
 progress but aims to handle most errors other than internal logic
 errors and ENOMEM more gracefully.

 This iteration prevents most crashes but can run into lockups with
 the page lock on occasion when the timing "works out."
