* NFS: Clean up inode metadata updatesTrond Myklebust2006-06-09

* NFSv4: Some NFSv4 servers have broken behaviour for the change attributeTrond Myklebust2006-06-09
| | | | | | | | | The Linux NFSv4 server violates RFC3530 in that the change attribute is not guaranteed to be updated for every change to the inode. Our optimisation for checking whether or not the inode metadata has changed or not is broken too. Grr.... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean up and fix page zeroing when we have short readsTrond Myklebust2006-06-09
| | | | | | | | | | | | | The code that is supposed to zero the uninitialised partial pages when the server returns a short read is currently broken: it looks at the nfs_page wb_pgbase and wb_bytes fields instead of the equivalent nfs_read_data values when deciding where to start truncating the page. Also ensure that we are more careful about setting PG_uptodate before retrying a short read: the retry will change the nfs_read_data args.pgbase and args.count.

* | | | [PATCH] debugfs inode leakJens Axboe2006-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Looking at the reiser4 crash, I found a leak in debugfs. In debugfs_mknod(), we create the inode before checking if the dentry already has one attached. We don't free it if that is the case. These bugs happen quite often, I'm starting to think we should disallow such coding in CodingStyle. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | | [PATCH] elevator switching raceJens Axboe2006-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a race between shutting down one io scheduler and firing up the next, in which a new io could enter and cause the io scheduler to be invoked with bad or NULL data. To fix this, we need to maintain the queue lock for a bit longer. Unfortunately we cannot do that, since the elevator init requires to be run without the lock held. This isn't easily fixable, without also changing the mempool API. So split the initialization into two parts, and alloc-init operation and an attach operation. Then we can preallocate the io scheduler and related structures, and run the attach inside the lock after we detach the old one. This patch has survived 30 minutes of 1 second io scheduler switching with a very busy io load. Signed-off-by: Jens Axboe <axboe@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Since the length is entirely arbitrary for a FIN packet carrying data, this is actually quite common. Unaligned data is not the end of the world, but we should avoid it if it's easily done. In this case it is trivial. Since we're discarding all of the head data it doesn't matter whether we move skb->data forward or back. However, it is still possible to have unaligned skb->data in general. So network drivers should be prepared to handle it instead of crashing. This patch also adds an unlikely marking on len < headlen since partial ACKs on head data are extremely rare in the wild. As the return value of __pskb_trim_head is no longer ever NULL that has been removed. Signed-off-by: Herbert Xu ~{PmV>HI~} <herbert@gondor.apana.org.au> Signed-off-by: David S.

* | | | [MIPS] Save write-only Config.OD from being clobberedSergei Shtylyov2006-06-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Save the Config.OD bit from being clobbered by coherency_setup(). This bit, when set, fixes various errata in the early steppings of Au1x00 SOCs. Unfortunately, the bit was write-only on the most early of them. In addition, also restore the bit after a wakeup from sleep. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The modpost uses a whitelist for commonly used suffix on checking the section mismatch. Adding "_ops" suffix to op_modex_xxx get rid of this modpost warning.
