do_kern_mount() does not allow the kernel to use private mount interfaces without exposing the same interfaces to userland. The problem is that the filesystem is referenced by name, thus meaning that it and its mount interface must be registered in the global filesystem list. vfs_kern_mount() passes the struct file_system_type as an explicit parameter in order to overcome this limitation.

Fix two errors in the client-side acl cache: First, when nfs3_proc_getacl requests only the default acl of a file and the access acl is not cached already, a NULL access acl entry is cached instead of ERR_PTR(-EAGAIN) ("not cached"). Second, update the cached acls in nfs3_proc_setacls: nfs_refresh_inode does not always invalidate the cached acls, and when it does not, the cached acls get out of sync.

Separate out the function of revalidating the inode metadata, and revalidating the mapping. The former may be called by lookup(), and only really needs to check that permissions, ctime, etc haven't changed whereas the latter needs only done when we want to read data from the page cache, and may need to sync and then invalidate the mapping.

The XID generator uses get_random_bytes to generate an initial XID. NFS_ROOT starts up before the random driver, though, so get_random_bytes doesn't set a random XID for NFS_ROOT. This causes NFS_ROOT mount points to reuse XIDs every time the client is booted. If the client boots often enough, the server will start serving old replies out of its DRC. Use net_random() instead. Test plan: I/O intensive workloads should perform well and generate no errors. Traces taken during client reboots should show that NFS_ROOT mounts use unique XIDs after every reboot.

Make the RPC client select privileged ephemeral source ports at random. This improves DRC behavior on the server by using the same port when reconnecting for the same mount point, but using a different port for fresh mounts. The Linux TCP implementation already does this for nonprivileged ports. Note that TCP sockets in TIME_WAIT will prevent quick reuse of a random ephemeral port number by leaving the port INUSE until the connection transitions out of TIME_WAIT. Test plan: Connectathon against every known server implementation using multiple mount points. Locking especially.

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: NTrond Myklebust <Trond.Myklebust@netapp.com>

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.

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: NJens Axboe <axboe@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

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: NJens Axboe <axboe@suse.de> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

From: "Andy Currid" <ACurrid@nvidia.com> This patch fixes a kernel panic during boot that occurs on NVIDIA platforms that have HPET enabled. When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is advertised as such in the ACPI APIC table - but an earlier workaround in the kernel was ignoring this override.
