Subject: reduce lookups in the COW extent tree V2
Date: Thu, 12 Jul 2018 15:49:04 +0200 [thread overview]
Message-ID: <20180712134910.30298-1-hch@lst.de> (raw)
This series (on top of the iomap series) reduce the number of lookups we
do in the COW tree by adding a sequence number that counts modifications
to the extent tree.
Changes since v1:
- don't update wpc->cow_seq for non-COW allocations
- update a comment
- rebase to the lastest tree as baseline
