The way how we process delayed refs is
1)get a bunch of head refs,
2)pick up one head ref,
3)go one node back for any delayed ref updates.
The head ref is also linked in the same rbtree as the delayed ref is,
so in 1) stage, we have to walk one by one including not only head refs, but
delayed
Data deduplication is a specialized data compression technique for eliminating
duplicate copies of repeating data.[1]
This patch set is also related to Content based storage in project ideas[2].
PATCH 1 is a hang fix with deduplication on, but it's also useful without
dedup in practice use.
When we have data deduplication on, we'll hang on the merge part
because it needs to verify every queued delayed data refs related to
this disk offset but we may have millions refs.
And in the case of delayed data refs, we don't usually have too much
data refs to merge.
So it's safe to shut it
This aims to add deduplication subcommand, 'btrfs dedup command path',
ie. register/unregister'.
It can be used to enable or disable dedup support for a filesystem.

While removing a file with dedup extents, we could have a great number of
delayed refs pending to process, and these refs refer to droping
a ref of the extent, which is of BTRFS_DROP_DELAYED_REF type.
But in order to prevent an extent's ref count from going down to zero when
there still are
So we don't need to do qgroups accounting trick without enabling quota.
This reduces my tester's costing time from ~28s to ~23s.

Please don't add more BUG_ON()s. They're unreliable because they can

If you *must* have logic asserts, use WARN_ON_ONCE and return errors.

For some time, I've successfully deployed btrfs send/receive as a

It's fast and flexible and nicely scriptable =)
