2006-02-03[PATCH] s390: dasd extended error reporting moduleStefan Weinhuber
The DASD extended error reporting is a facility that allows to get detailed information about certain problems in the DASD I/O. This information can be used to implement fail-over applications that can recover these problems.

2006-02-03[PATCH] ide: restore support for AEC6280M cards in aec62xx.cThibaut VARENE
This patch adds missing initialization sequence, necessary to get the "Macintosh" version of AEC6280 cards to work in Linux. Without this patch, the driver hangs for several minutes trying to initialize the card and the kernel is left in an unstable state. This patch has been tested fine on ppc and i386.

2006-02-03[PATCH] Kprobes: Fix deadlock in function-return probesAnanth N Mavinakayanahalli
When two function-return probes are inserted on kfree()[1] and the second on say, sys_link()[2], and later [2] is unregistered, we have a deadlock as kfree is called with the kretprobe_lock held and the function-return probe on kfree will also try to grab the same lock. However, we can move the kfree() during unregistration to outside the spinlock as we are sure that no instances from the free list will be used after synchronized_sched() returns during the unregistration process. Thanks to Masami Hiramatsu for spotting this.

2006-02-03[PATCH] md: Handle overflow of mdu_array_info_t->size betterNeilBrown
mdu_array_info_t->size is 'int', which isn't big enough for the size (in KB of each component in) some arrays. So rather than a random overflow, set size to -1 when it cannot be set correctly. To update aspect on an array, userspace will sometimes: get_array_info change one field set_array_info in this case, we don't want the '-1' in 'size' to change to size, or look like a size change at all. So test for that in update_array_info. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-02-02[PATCH] md: Fix device-size updates in mdNeilBrown
As 'array_size' is a 'sector_t', it may overflow inappropriately when shifted 10 bits. So We should cast it to a loff_t first. There are two places with this problem, but the second (in update_raid_disks) isn't needed so just remove it: The only personality that handles ->reshape currently is raid1, and it doesn't change the size of the array. When added for raid5/6, reshape again won't change the size of the array, at least not straight away. This code might be need for reshaping 'linear' but linear->shape, if implemented, should probably do the i_size_write itself.

2006-02-01[PATCH] compat: fix compat_sys_openat and friendsStephen Rothwell
Most of the 64 bit architectures will zero extend the first argument to compat_sys_{openat,newfstatat,futimesat} which will fail if the 32 bit syscall was passed AT_FDCWD (which is a small negative number). Declare the first argument to be an unsigned int which will force the correct sign extension when the internal functions are called in each case.

2006-02-01SUNRPC: Fix a lock recursion in the auth_gss downcallTrond Myklebust
When we look up a new cred in the auth_gss downcall so that we can stuff the credcache, we do not want that lookup to queue up an upcall in order to initialise it. To do an upcall here not only redundant, but since we are already holding the inode->i_mutex, it will trigger a lock recursion. This patch allows rpcauth cache searches to indicate that they can cope with uninitialised credentials. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-02-01NLM: Ensure that nlmclnt_cancel_callback() doesn't loop foreverTrond Myklebust
