Subject: [PATCH 0/4] shmem: radix-tree cleanups and swapoff optimizations
Date: Fri, 10 Feb 2012 23:42:18 +0400 [thread overview]
Message-ID: <20120210193249.6492.18768.stgit@zurg> (raw)
Here some shmem patches related to the radix-tree iterator patchset,
they cleans radix-tree usage in shmem and notably optimizes swapoff operation.
Last patch is slightly off-topic, but it shares test results with previous patch.
---
Konstantin Khlebnikov (4):
shmem: simlify shmem_unlock_mapping
shmem: tag swap entries in radix tree
shmem: use radix-tree iterator in shmem_unuse_inode()
mm: use swap readahead at swapoff
