btrfs: expand btrfs_find_item() to include find_root_ref functionality

2014-01-28T21:19:36+00:00

This patch is the second step in bootstrapping the btrfs_find_item
interface. The btrfs_find_root_ref() is similar to the former
__inode_info(); it accepts four of its parameters, and duplicates the
first half of its functionality.

Replace the one former call to btrfs_find_root_ref() with a call to
btrfs_find_item(), along with the defined key type that was used
internally by btrfs_find_root ref, and a null found key. In
btrfs_find_item(), add a test for the null key at the place where
the functionality of btrfs_find_root_ref() ends; btrfs_find_item()
then returns if the test passes. Finally, remove btrfs_find_root_ref().

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.

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.  Thanks,
