Duncan says it\nappeared to be a regression of 3.6-rc1 and couldn\u0027t reproduce it on\n3.5. Bisection seemed to point to 63d95a91 \"workqueue: use @pool\ninstead of @gcwq or @cpu where applicable\" which is an non-functional\nchange.

These are all\n related to the block reservation code which was added at the merge\n window. That code will be getting an update at the forthcoming merge\n window too. In the mean time though there are a few smaller issues\n which should be fixed.\n\n The first patch resolves an issue with write sizes of greater than 32\n bits with the size hinting code. The second ensures that the\n allocation data structure is initialised when using xattrs and the\n third takes into account allocations which may have been made by other\n nodes which affect a reservation on the local node.\"\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes:\n GFS2: Take account of blockages when using reserved blocks\n GFS2: Fix missing allocation data for set/remove xattr\n GFS2: Make write size hinting code common\n" } ], "next": "9cb0ee8576eabb52ad5aad347bf0aaf997975bba" }
