From 70e60ce71516c3a9e882edb70a09f696a05961db Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 20 Jul 2010 08:07:02 +1000 Subject: xfs: convert inode shrinker to per-filesystem contexts Now the shrinker passes us a context, wire up a shrinker context per filesystem. This allows us to remove the global mount list and the locking problems that introduced. It also means that a shrinker call does not need to traverse clean filesystems before finding a filesystem with reclaimable inodes. This significantly reduces scanning overhead when lots of filesystems are present.

No need to start another asynchronous writeback inside ->put_super.
