Date: Tue, 10 Mar 2015 15:45:15 -0400 From: Josef Bacik <jbacik@...com> To: <linux-fsdevel@...r.kernel.org>, <david@...morbit.com>, <viro@...iv.linux.org.uk>, <jack@...e.cz>, <linux-kernel@...r.kernel.org> Subject: [PATCH 0/9] Sync and VFS scalability improvements These are patches that Dave Chinner wrote two years ago that are still very much needed today. I recently ran into a problem where I had millions of inodes that needed to be evicted at unmount time and it soft locked up the box and kept any other file system from doing work. These patches fix this problem by breaking the inode_sb_list_lock into per-sb, and then converting the per sb inode list into a list_lru for better scalability. I've also pulled forward Dave's sync scalability patches which still seem pretty relevant. I had to fix a couple of these to bring them forward but I touched very little and I've preserved the authorship of everything. I added the Reviewed-by's that were there when the patches were originally submitted. I've run this through xfstests on btrfs and xfs and verified that everything seems to be working. If you are interested the original submission can be found here http://lwn.net/Articles/561569/ Finally the last patch is from me and this fixes the softlockup problems I was seeing on unmount with a large amount of inodes that needed to be evicted.
