I have gotten to the root cause of the hugetlb badness I reported back on August 15th. My system has the following memory topology (note the overlapping node): Node 0 Memory: 0x8000000-0x44000000 Node 1 Memory: 0x0-0x8000000 0x44000000-0x80000000 setup_zone_migrate_reserve() scans the address range 0x0-0x8000000 looking for a pageblock to move onto the MIGRATE_RESERVE list. Finding no candidates, it happily continues the scan into 0x8000000-0x44000000. When a pageblock is found, the pages are moved to the MIGRATE_RESERVE list on the wrong zone. Oops. setup_zone_migrate_reserve() should skip pageblocks in overlapping nodes.

Breaking lines due to some imaginary problem with a long line length is often stupid and wrong, but never more so when it splits a string that is printed out into multiple lines. This really ended up making it much harder to find where some error strings were printed out, because a simple 'grep' didn't work. I'm sure there is tons more of this particular idiocy hiding in other places, but this particular case hit me once more last week. So fix it.

The MEMGETREGIONINFO ioctl() in mtdchar.c was clobbering user memory by overwriting more than intended, due the size of struct mtd_erase_region_info changing in commit 0ecbc81a ('Support for auto locking flash on power up'). Fix avoids this by copying struct members one by one with put_user(), as there is no longer a convenient struct to use the size of as the length argument to copy_to_user().

David Wagner added (among other things) that copy_to_user could be probably used here. Ingo Oeser suggested to use simple_read_from_buffer() here. The conclusion is that proc_do_xprt doesn't check for userside buffer size indeed so fix this by using Ingo's suggestion.

/proc/partitions didn't use to write out the header if there was no partition. However, recent commit 66c64afe changed the behavior. This is nothing major but there's no reason to change user visible behavior without a good rationale. Restore the original behavior. Note that 2.6.28 has clean up changes scheduled which will replace this rather hacky implementation.

A recent patch to protect the rdev list with rcu locking leaves us with a problem because we can sleep on memalloc while holding the rcu lock. The rcu lock is only needed while walking the linked list as uninteresting devices (failed or spares) can be removed at any time. So only take the rcu lock while actually walking the linked list. Take a refcount on the rdev during the time when we drop the lock and do the memalloc to start IO. When we return to the locked code, all the interesting devices on the list will not have moved, so we can simply use list_for_each_continue_rcu to pick up where we left off.

When stopping an md array, or just switching to read-only, we currently call invalidate_partition while holding the mddev lock. The main reason for this is probably to ensure all dirty buffers are flushed (invalidate_partition calls fsync_bdev). However if any dirty buffers are found, it will almost certainly cause a deadlock as starting writeout will require an update to the superblock, and performing that updates requires taking the mddev lock - which is already held. This deadlock can be demonstrated by running "reboot -f -n" with a root filesystem on md/raid, and some dirty buffers in memory. All other calls to stop an array should already happen after a flush. The normal sequence is to stop using the array (e.g. umount) which will cause __blkdev_put to call sync_blockdev. Then open the array and issue the STOP_ARRAY ioctl while the buffers are all still clean. So this invalidate_partition is normally a no-op, except for one case where it will cause a deadlock. So remove it. This patch possibly addresses the regression recored in http://bugzilla.kernel.org/show_bug.cgi?id=11460 and http://bugzilla.kernel.org/show_bug.cgi?id=11452 though it isn't yet clear how it ever worked.
