These have already been discussed in a lkml thread for a while, so I wanted to formally send them out. The problem was that as part of a AIM7 regression we saw that we spend a lot of time looking up extent records. I turns out that the current delayed write path is horribly inefficient, and we can generall do with a single btree lookup for the write path. Also xfs_inode_set_eofblocks_tag turns out to trash the cache quite bad, so add a trivial flag to avoid it if we can. Compared to the git tree under discussion only one changelog has been updated, and I've added a copyright statement to xfs_iomap.c now that it has a lot of my code. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
