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.

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."

btrfs: btrfs_drop_snapshot should return int

2012-03-22T00:45:36+00:00

Commit cb1b69f4 (Btrfs: forced readonly when btrfs_drop_snapshot() fails)
made btrfs_drop_snapshot return void because there were no callers checking
the return value. That is the wrong order to handle error propogation since
the caller will have no idea that an error has occured and continue on
as if nothing went wrong.

btrfs: drop gfp_t from lock_extent

2012-03-22T00:45:35+00:00

 lock_extent and unlock_extent are always called with GFP_NOFS, drop the
 argument and use GFP_NOFS consistently.

btrfs: __add_reloc_root error push-up

2012-03-22T00:45:34+00:00

This patch pushes kmalloc errors up to the caller and BUGs in the caller.

The BUG_ON for duplicate reloc tree root insertion is replaced with a
panic explaining the issue.

btrfs: Panic on bad rbtree operations

2012-03-22T00:45:30+00:00

The ordered data and relocation trees have BUG_ONs to protect against
bad tree operations.

This patch replaces them with a panic that will report the problem.
