Btrfs: insert orphan roots into fs radix tree

2013-10-11T01:30:53+00:00

Now we don't drop all the deleted snapshots/subvolumes before the space balance. It means we have to relocate the space which is held by the dead snapshots/subvolumes. So we must into them into fs radix tree, or we would forget to commit the change of them when doing transaction commit, and it would corrupt the metadata.

Btrfs: Remove superfluous casts from u64 to unsigned long long

2013-09-01T12:16:08+00:00

u64 is "unsigned long long" on all architectures now, so there's no need to cast it when formatting it using the "ll" length modifier. Signed-off-by: Geert Uytterhoeven Signed-off-by: Josef Bacik Signed-off-by: Chris Mason

btrfs: Cleanup for using BTRFS_SETGET_STACK instead of raw convert

2013-09-01T11:57:37+00:00

Some codes still use the cpu_to_lexx instead of the BTRFS_SETGET_STACK_FUNCS declared in ctree.h. Also added some BTRFS_SETGET_STACK_FUNCS for btrfs_header btrfs_timespec and other structures.

Btrfs: cleanup orphaned root orphan item

2013-07-02T15:50:52+00:00

I hit a weird problem were my root item had been deleted but the orphan item had not. This isn't necessarily a problem, but it keeps the file system from being mounted. To fix this we just need to axe the orphan item if we can't find the fs root when we're putting them altogether. With this patch I was able to successfully mount my file system.

Btrfs: cleanup the similar code of the fs root read

2013-06-14T15:29:37+00:00

There are several functions whose code is similar, such as btrfs_find_last_root() btrfs_read_fs_root_no_radix() Besides that, some functions are invoked twice, it is unnecessary, for example, we are sure that all roots which is found in btrfs_find_orphan_roots() have their orphan items, so it is unnecessary to check the orphan item again. So cleanup it. Signed-off-by: Miao Xie Signed-off-by: Josef Bacik

Btrfs: rename root_times_lock to root_item_lock

2012-12-17T01:46:21+00:00

Originally root_times_lock was introduced as part of send/receive code however newly developed patch to label the subvol reused the same lock, so renaming it for a meaningful name. Signed-off-by: Anand Jain Signed-off-by: Chris Mason

btrfs: move transaction aborts to the point of failure

2012-10-09T00:09:02+00:00

Call btrfs_abort_transaction as early as possible when an error condition is detected, that way the line number reported is useful and we're not clueless anymore which error path led to the abort. Signed-off-by: David Sterba
