| H A D | extents_status.h | 2be12de9 Tue Nov 25 10:55:24 CST 2014 Jan Kara <jack@suse.cz> ext4: introduce aging to extent status tree
Introduce a simple aging to extent status tree. Each extent has a
REFERENCED bit which gets set when the extent is used. Shrinker then
skips entries with referenced bit set and clears the bit. Thus
frequently used extents have higher chances of staying in memory.
