2010-04-06libata: unlock HPA if device shrunkTejun Heo
Some BIOSes don't configure HPA during boot but do so while resuming. This causes harddrives to shrink during resume making libata detach and reattach them. This can be worked around by unlocking HPA if old size equals native size. Add ATA_DFLAG_UNLOCK_HPA so that HPA unlocking can be controlled per-device and update ata_dev_revalidate() such that it sets ATA_DFLAG_UNLOCK_HPA and fails with -EIO when the above condition is detected. This patch fixes the following bug. https://bugzilla.kernel.org/show_bug.cgi?id=15396 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Oleksandr Yermolenko <yaa.bta@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2010-04-06libata: disable NCQ on Crucial C300 SSDTejun Heo
Crucial said, Thank you for contacting us. We know that with our M225 line of SSDs you sometimes need to disable NCQ (native command queuing) to avoid just the type of errors you're seeing. Our recommendation for the M225 is to add libata.force=noncq to your Linux kernel boot options, under the kernel ATA library option. I have sent your feedback to the engineers working on the C300, and asked them to please pass it on to the firmware team. I have been notified that they are in the process of testing and finalizing a new firmware version, that you can expect to see released around the end of April. We’ll keep you posted as to when it will be available for download. So, turn off NCQ on the drive w/ the current firmware revision.

2010-04-05Fix up possibly racy module refcountingNick Piggin
Module refcounting is implemented with a per-cpu counter for speed. However there is a race when tallying the counter where a reference may be taken by one CPU and released by another. Reference count summation may then see the decrement without having seen the previous increment, leading to lower than expected count. A module which never has its actual reference drop below 1 may return a reference count of 0 due to this race. Module removal generally runs under stop_machine, which prevents this race causing bugs due to removal of in-use modules. However there are other real bugs in module.c code and driver code (module_refcount is exported) where the callers do not run under stop_machine. Fix this by maintaining running per-cpu counters for the number of module refcount increments and the number of refcount decrements. The increments are tallied after the decrements, so any decrement seen will always have its corresponding increment counted. The final refcount is the difference of the total increments and decrements, preventing a low-refcount from being returned.

2010-04-05audit: preface audit printk with auditEric Paris
There have been a number of reports of people seeing the message: "name_count maxed, losing inode data: dev=00:05, inode=3185" in dmesg. These usually lead to people reporting problems to the filesystem group who are in turn clueless what they mean. Eventually someone finds me and I explain what is going on and that these come from the audit system. The basics of the problem is that the audit subsystem never expects a single syscall to 'interact' (for some wish washy meaning of interact) with more than 20 inodes. But in fact some operations like loading kernel modules can cause changes to lots of inodes in debugfs. There are a couple real fixes being bandied about including removing the fixed compile time limit of 20 or not auditing changes in debugfs (or both) but neither are small and obvious so I am not sending them for immediate inclusion (I hope Al forwards a real solution next devel window). In the meantime this patch simply adds 'audit' to the beginning of the crap message so if a user sees it, they come blame me first and we can talk about what it means and make sure we understand all of the reasons it can happen and make sure this gets solved correctly in the long run.

2010-04-05Btrfs: add check for changed leaves in setup_leaf_for_splitChris Mason
setup_leaf_for_split needs to drop the path and search again, and has checks to see if the item we want to split changed size. But, it misses the case where the leaf changed and now has enough room for the item we want to insert. This adds an extra check to make sure the leaf really needs splitting before we call btrfs_split_leaf(), which keeps us from trying to split a leaf with a single item. btrfs_split_leaf() will blindly split the single item leaf, leaving us with one good leaf and one empty leaf and then a crash.

2010-04-05Btrfs: create snapshot references in same commit as snapshotSage Weil
This creates the reference to a new snapshot in the same commit as the snapshot itself. This avoids the need for a second commit in order for a snapshot to be persistent, and also avoids the problem of "leaking" a new snapshot tree root if the host crashes before the second commit takes place. It is not at all clear to me why it wasn't always done this way. If there is still a reason for the two-stage {create,finish}_pending_snapshots() approach I'm missing something! :) I've been running this for a couple weeks under pretty heavy usage (a few snapshots per minute) without obvious problems.

2010-04-05Btrfs: fix small race with delalloc flushing waitqueue'sJosef Bacik
Everytime we start a new flushing thread, we init the waitqueue if there isn't a flushing thread running. The problem with this is we check space_info->flushing, which we clear right before doing a wake_up on the flushing waitqueue, which causes problems if we init the waitqueue in the middle of clearing the flushing flagh and calling wake_up. This is hard to hit, but the code is wrong anyway, so init the flushing/allocating waitqueue when creating the space info and let it be. I haven't seen the panic since I've been using this patch.

2010-04-05Btrfs: use add_to_page_cache_lru, use __page_cache_allocNick Piggin
Pagecache pages should be allocated with __page_cache_alloc, so they obey pagecache memory policies. add_to_page_cache_lru is exported, so it should be used. Benefits over using a private pagevec: neater code, 128 bytes fewer stack used, percpu lru ordering is preserved, and finally don't need to flush pagevec before returning so batching may be shared with other LRU insertions.
