The standard ACPI dock driver can handle the hotplug bays and docks of the ThinkPads just fine (including batteries) as of 2.6.27, and the code in thinkpad-acpi for the dock and bay subdrivers is currently broken anyway... Userspace needs some love to support the two-stage ejection nicely, but it is simple enough to do through udev rules (you don't even need HAL) so this wouldn't justify fixing the dock and bay subdrivers, either. That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well as support for the weird dock of the model 570, but since such support has never left the "experimental" stage, it is also not a strong enough reason to find a way to fix this code. Users of ThinkPads with warm-swap bays are urged to request that _EJ3 support be added to the regular ACPI dock driver, if such feature is indeed useful for them.

Currently, the ThinkPad-ACPI bay and dock drivers are completely broken, and cause a NULL pointer derreference in kernel mode (and, therefore, an OOPS) when they try to issue events (i.e. on dock, undock, bay ejection, etc). OTOH, the standard ACPI dock driver can handle the hotplug bays and docks of the ThinkPads just fine (including batteries) as of 2.6.27. In fact, it does a much better job of it than thinkpad-acpi ever did. It is just not worth the hassle to find a way to fix this crap without breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old, deprecated code that sees little testing or use. As a quick fix suitable for -stable backports, mark the thinkpad-acpi bay and dock subdrivers as BROKEN in Kconfig. The dead code will be removed by a later patch. This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

commit 6321e3ed caused the full bmv_count's worth of getbmapx structures to get allocated; telling it to do MAXEXTNUM was a bit insane, resulting in ENOMEM every time. Chop it down to something reasonable, the number of slots in the caller's input buffer. If this is too large the caller may get ENOMEM but the reason should not be a mystery, and they can try again with something smaller. We add 1 to the value because in the normal getbmap world, bmv_count includes the header and xfs_getbmap does: nex = bmv->bmv_count - 1; if (nex <= 0) return XFS_ERROR(EINVAL); Signed-off-by: NEric Sandeen <sandeen@sandeen.net> Reviewed-by: NOlaf Weber <olaf@sgi.com> Reviewed-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NFelix Blyakher <felixb@sgi.com>

The async block group caching code uses the commit_root pointer to get a stable version of the extent allocation tree for scanning. This copy of the tree root isn't going to change and it significantly reduces the complexity of the scanning code. During a commit, we have a loop where we update the extent allocation tree root. We need to loop because updating the root pointer in the tree of tree roots may allocate blocks which may change the extent allocation tree. Right now the commit_root pointer is changed inside this loop. It is more correct to change the commit_root pointer only after all the looping is done.

When a file is deleted from a gfs2 filesystem on one node, a dcache entry for it may still exist on other nodes in the cluster. If this happens, gfs2 will be unable to free this file on disk. Because of this, it's possible to have a gfs2 filesystem with no files on it and no free space. With this patch, when a node receives a callback notifying it that the file is being deleted on another node, it schedules a new workqueue thread to remove the file's dcache entry.

Since both linked and unlinked inodes are counted by rgd->rd_dinodes, It makes no sense to count them with the used data blocks (first check that I changed), it makes sense to count them with the linked inodes (second check), and it makes no sense to care if there are more unlinked inodes than linked ones.

GFS2 was placing far too many glocks on the reclaim list that were not good candidates for freeing up from cache. These locks would sit there and repeatedly get scanned to see if they could be reclaimed, wasting a lot of time when there was memory pressure. This fix does more checks on the locks to see if they are actually likely to be removable from cache.
