This little debugging __get_user is in fact happening inside a spinlock. It was never very useful, and has caused problems for some architectures in the past. Let's just remove it. Signed-off-by:

CC mm/slab.o mm/slab.c: In function `kmem_cache_create': mm/slab.c:1129: warning: comparison of unsigned expression < 0 is always false This comes from the fact that 'align' is size_t and so unsigned. Just to be sure, I did $ grep __kernel_size_t include/*/posix_types.h and yes, every arch defines that to be unsigned. Signed-off-by:

From: David Gibson <david@gibson.dropbear.id.au> This patch excludes the .pc directory from the same things that SCCS/BitKeeper/.svn/CVS files are excluded from. The .pc directory is used for backup/reference files by quilt, a patch mangling system conceptually derived from akpm's patch scripts. Excluding the .pc directory is handy, because otherwise old versions of files found in there tend to end up at the front of the TAGS index. Signed-off-by:

From: <adobriyan@mail.ru> Imagine you have a code similar to struct foo { union { struct tcphdr *th; } h; union { struct iphdr *iph; } nh; }; kernel-doc in it's current state will happily eat everything from first '{' to last '}' and nobody will see parameter 'h' in documentation (look at include/linux/skbuff.h:struct sk_buff for real world example). So, fix the greedy regexp. Signed-off-by: -

CC [M] fs/smbfs/proc.o fs/smbfs/proc.c: In function `smb_proc_readdir_long': fs/smbfs/proc.c:2313: warning: comparison of unsigned expression < 0 is always false fs/smbfs/proc.c:2467: warning: comparison of unsigned expression < 0 is always false The first one is pretty dangerous looking, as smb_proc_readdir_long() can return several negative error values and all those are converted to unsigned and then erronously pass the test on line 2313. Chris Wright gave it a quick look and we did not see immediately if this can be remotely exploited, but it looks pretty scary. The second warning on line 2467 is just extra so I just removed it.

nfsd currently just sets f_pos when seeking in a directory. This bypasses any checking and other handling that a filesystem might want to do. So instead, we define "vfs_llseek" to be an exported "llseek", and use that, both to seek at the start, and the find the new position at the end.

Here's a patch to allow the kAFS filesystem to use the automount facility patch presented in a previous email. It allows me to mount an AFS root volume on /afs and then just walk through the directory structure causing referenced volumes to be automounted and autoumounted. For instance, if I do: [root@andromeda root]# mount -t afs \#root.afs. /afs [root@andromeda root]# ls /afs asd cambridge cambridge.redhat.com grand.central.org [root@andromeda root]# ls /afs/cambridge afsdoc [root@andromeda root]# ls /afs/cambridge/afsdoc/ ChangeLog html LICENSE pdf RELNOTES-1.2.2 And then look in the mountpoint catalogue, I see: [root@andromeda root]# cat /proc/mounts ... #root.afs. /afs afs rw 0 0 #root.cell. /afs/cambridge.redhat.com afs rw 0 0 #afsdoc. /afs/cambridge.redhat.com/afsdoc afs rw 0 0 Then after waiting a few minutes: [root@andromeda root]# cat /proc/mounts ... #root.afs. /afs afs rw 0 0 Is all that remains.

Here's a patch that I worked out with Al Viro that adds support for a filesystem (such as kAFS) to perform automounting intrinsically without the need for a userspace daemon. It also adds support for such mountpoints to be degraded at the filesystem's behest until they've been untouched long enough that they'll be removed. I've a patch (to follow) that removes some #ifdef's from fs/afs/* thus allowing it to make use of this facility. There are five pieces to this: (1) Any interested filesystem needs to have at least one list to which expirable mountpoints can be added. Access to this list is governed by the vfsmount_lock. (2) When a filesystem wants to create an expirable mount, it calls do_kern_mount() to get a handle on the filesystem it wants mounting, and then calls do_add_mount() to mount that filesystem on the designated mountpoint, supplying the list mentioned in (1) to which the vfsmount will be added. In kAFS's case, the mountpoint is a directory with a follow_link() method defined (fs/afs/mntpt.c). This uses the struct nameidata supplied as an argument as a determination of where the new filesystem should be mounted. (3) When something using a vfsmount finishes dealing with it, it calls mntput(). This unmarks the vfsmount for immediate expiry. There are two criteria for determining if a vfsmount may be expired - it mustn't be marked as in use for anything other than being a child of another vfsmount, and it must have an expiry mark against it already. (4) The filesystem then determines the policy on expiring the mounts created in (2). When it feels the need to, it passes the list mentioned in (1) to mark_mounts_for_expiry() to request everything on the list be expired. This function examines each mount listed. If the vfsmount meets the criteria mentioned in (3), then the vfsmount is deleted from the namespace and disposed of as for unmounting; otherwise the vfsmount is left untouched apart from now bearing an expiration mark if it didn't before. kAFS's expiration policy is simply to invoke this process at regular intervals for all the mounts on its list. (5) An expiration facility is also provided to userspace: by calling umount() with a MNT_EXPIRE flag, it can make a request to unmount only if the mountpoint hasn't been used since the last request and isn't in use now. This allows expiration to be driven by userspace instead of by the kernel if that is desirable. This also means that do_umount() has to use a different version of path_release() to everyone else... it can't call mntput() as that clears the expiration flag, thus rendering this unachievable; so it's version of path_release() calls _mntput(), which doesn't do the clear. My original idea was to give the kernel more knowledge of automounted things. This avoids a certain problem with stat() on a mountpoint causing it to mount (for example, do "ls -l /afs" on a machine with kAFS), but Al wanted it done this way. > Why is autofs unsuitable? Because: (1) Autofs is flat; AFS requires a tree - mounts on mounts on mounts on mounts... (2) AFS holds the data as to what the mountpoints are and where they go, and these may be cross-links to subtrees beyond your control. It's also not trivial to extract a list of mountpoints as is required for autofs. (3) Autofs is not namespace safe. (4) Ducking back to userspace to get that to do the mount is pretty tricky if namespaces are involved. In fact, autofs may well want to make use of this facility. Signed-Off-By: -

From: Will Schmidt <willschm@us.ibm.com> This patch includes updates and cleanup for the PPC64 proc/lparcfg interface. - use seq_file's seq_printf for output - remove redundant e2a function. (use viopath.c's instead) - change to Kconfig to allow building as a module. - export required symbols from LparData.c Pass # 2 updates.. - Per Pauls request I've removed the vpurr references, and left just a stub function get_purr(). - this should apply clean to latest linus tree. (test-applied against 2.6.7-rc3). Pass # 3 updates... - Correcting my previously incorrect description of the lparcfg_count_active_processors() function.. This is for the cases where we have some number of virtual processors that are different than the total number of threads in the system. (i.e. systemcfg->processorcount isnt the desired value for partition_active_processors) - moved e2a function into its own file in arch/ppc64/lib. - changed lparcfg_count_active_processors() to use a while loop instead of a for loop. - removed redundant of_node_put in lparcfg_count_active_processors(). - removed unneeded parms from get-system-parameter rtas_call.

On recent pSeries systems, EEH needs to be enabled even on PCI Host Bridges (PHB's). If not enabled, then ordinary PCI probing (config-space reads/writes to the bridges) will generate firmware error messages, possibly a very large number of messages for systems with large numbers of pci slots.

The patch fixes locking of i_flags. It removes S_QUOTA flag from i_flags because it was almost unused and updating it on some places correctly (under i_sem) would be tricky. Note that accessing of S_NOQUOTA flag is serialized by dqptr_sem and so we can reliably tested without i_sem. Signed-off-by:

Apparantly, the reason for this change is that it gives "much less NFS stalls with a SMC91C96 on a 10/100MB switch." Alan Cox's comments on this is: "spec says 16 collision retries max _ever_. I bet his 'broken switch' is a case of half v full duplex" and a recommendation to remove it. Also, since the change does not limit the number of times we may retry to send the packet, I think this code opens a potential DoS attack against network which has a machine connected running this code.
