From 6bfb3d065f4c498c17a3a07f3dc08cedff53aff4 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 30 Oct 2008 18:32:43 +1100 Subject: [XFS] Fix race when looking up reclaimable inodes If we get a race looking up a reclaimable inode, we can end up with the winner proceeding to use the inode before it has been completely re-initialised. This is a Bad Thing. Fix the race by checking whether we are still initialising the inod eonce we have a reference to it, and if so wait for the initialisation to complete before continuing. While there, fix a leaked reference count in the same code when encountering an unlinked inode and we are not doing a lookup for a create operation.
