2008-11-16e1000: Use device_set_wakeup_enable\"Rafael J. Wysocki\
Since dev->power.should_wakeup bit is used by the PCI core to decide whether the device should wake up the system from sleep states, set/unset this bit whenever WOL is enabled/disabled using e1000_set_wol(). Accordingly, use device_can_wakeup() for checking if wake-up is supported by the device. Signed-off-by: "Rafael J.

2008-11-16function tracing: fix wrong pos computing when read buffer has been fulfilledwalimis
Impact: make output of available_filter_functions complete phenomenon: The first value of dyn_ftrace_total_info is not equal with `cat available_filter_functions | wc -l`, but they should be equal. root cause: When printing functions with seq_printf in t_show, if the read buffer is just overflowed by current function record, then this function won't be printed to user space through read buffer, it will just be dropped. So we can't see this function printing. So, every time the last function to fill the read buffer, if overflowed, will be dropped. This also applies to set_ftrace_filter if set_ftrace_filter has more bytes than read buffer. fix: Through checking return value of seq_printf, if less than 0, we know this function doesn't be printed. Then we decrease position to force this function to be printed next time, in next read buffer. Another little fix is to show correct allocating pages count.

2008-11-15Fix inotify watch removal/umount racesAl Viro
Inotify watch removals suck violently. To kick the watch out we need (in this order) inode->inotify_mutex and ih->mutex. That's fine if we have a hold on inode; however, for all other cases we need to make damn sure we don't race with umount. We can *NOT* just grab a reference to a watch - inotify_unmount_inodes() will happily sail past it and we'll end with reference to inode potentially outliving its superblock. Ideally we just want to grab an active reference to superblock if we can; that will make sure we won't go into inotify_umount_inodes() until we are done. Cleanup is just deactivate_super(). However, that leaves a messy case - what if we *are* racing with umount() and active references to superblock can't be acquired anymore? We can bump ->s_count, grab ->s_umount, which will almost certainly wait until the superblock is shut down and the watch in question is pining for fjords. That's fine, but there is a problem - we might have hit the window between ->s_active getting to 0 / ->s_count - below S_BIAS (i.e. the moment when superblock is past the point of no return and is heading for shutdown) and the moment when deactivate_super() acquires ->s_umount. We could just do drop_super() yield() and retry, but that's rather antisocial and this stuff is luser-triggerable. OTOH, having grabbed ->s_umount and having found that we'd got there first (i.e. that ->s_root is non-NULL) we know that we won't race with inotify_umount_inodes(). So we could grab a reference to watch and do the rest as above, just with drop_super() instead of deactivate_super(), right? Wrong. We had to drop ih->mutex before we could grab ->s_umount. So the watch could've been gone already. That still can be dealt with - we need to save watch->wd, do idr_find() and compare its result with our pointer. If they match, we either have the damn thing still alive or we'd lost not one but two races at once, the watch had been killed and a new one got created with the same ->wd at the same address. That couldn't have happened in inotify_destroy(), but inotify_rm_wd() could run into that. Still, "new one got created" is not a problem - we have every right to kill it or leave it alone, whatever's more convenient. So we can use idr_find(...) == watch && watch->inode->i_sb == sb as "grab it and kill it" check. If it's been our original watch, we are fine, if it's a newcomer - nevermind, just pretend that we'd won the race and kill the fscker anyway; we are safe since we know that its superblock won't be going away. And yes, this is far beyond mere "not very pretty"; so's the entire concept of inotify to start with.

2008-11-15Add 'pr_fmt()' format modifier to pr_xyz macros.Martin Schwidefsky
A common reason for device drivers to implement their own printk macros is the lack of a printk prefix with the standard pr_xyz macros. Introduce a pr_fmt() macro that is applied for every pr_xyz macro to the format string. The most common use of the pr_fmt macro would be to add the name of the device driver to all pr_xyz messages in a source file.

We do this by abandoning the global list of SMB sessions and instead moving to a per-server list. This entails adding a new list head to the TCP_Server_Info struct. The refcounting for the cifsSesInfo is moved to a non-atomic variable. We have to protect it by a lock anyway, so there's no benefit to making it an atomic. The list and refcount are protected by the global cifs_tcp_ses_lock. The patch also adds a new routines to find and put SMB sessions and that properly take and put references under the lock.

2008-11-14libata: improve phantom device detectionTejun Heo
Currently libata uses four methods to detect device presence. 1. PHY status if available. 2. TF register R/W test (only promotes presence, never demotes) 3. device signature after reset 4. IDENTIFY failure detection in SFF state machine Combination of the above works well in most cases but recently there have been a few reports where a phantom device causes unnecessary delay during probe. In both cases, PHY status wasn't available. In one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which didn't qualify as #4. The other failed #2 but as it passed #3 and #4, it still caused failure. In both cases, phantom device reported diagnostic failure, so these cases can be safely worked around by considering any !ATA_DRQ IDENTIFY failure as NODEV_HINT if diagnostic failure is set.

We want to continue to share TCP sessions, however since they are required for multiuser mounts. For that, implement a new (hopefully race-free) scheme. Add a new global list of TCP sessions, and take care to get a reference to it whenever we're dealing with one.

2008-11-14net/ucc_geth: Fix oops in uec_get_ethtool_stats()Anton Vorontsov
p_{tx,rx}_fw_statistics_pram are special: they're available only when a device is open. If the device is closed, we should just fill the data with zeroes. Fixes the following oops: root@b1:~# ifconfig eth1 down root@b1:~# ethtool -S eth1 Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc01e1dcc Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01e1dcc] uec_get_ethtool_stats+0x98/0x124 LR [c0287cc8] ethtool_get_stats+0xfc/0x23c Call Trace: [cfaadde0] [c0287ca8] ethtool_get_stats+0xdc/0x23c (unreliable) [cfaade20] [c0288340] dev_ethtool+0x2fc/0x588 [cfaade50] [c0285648] dev_ioctl+0x290/0x33c [cfaadea0] [c0272238] sock_ioctl+0x80/0x2ec [cfaadec0] [c00b5ae4] vfs_ioctl+0x40/0xc0 [cfaadee0] [c00b5fa8] do_vfs_ioctl+0x78/0x20c [cfaadf10] [c00b617c] sys_ioctl+0x40/0x74 [cfaadf40] [c00142d8] ret_from_syscall+0x0/0x38 [...] ---[ end trace b941007b2dfb9759 ]--- Segmentation fault p.s.

2008-11-14scm: fix scm_fp_list->list initialization made in wrong placePavel Emelyanov
This is the next page of the scm recursion story (the commit f8d570a4 net: Fix recursive descent in __scm_destroy()). In function scm_fp_dup(), the INIT_LIST_HEAD(&fpl->list) of newly created fpl is done *before* the subsequent memcpy from the old structure and thus the freshly initialized list is overwritten. But that's OK, since this initialization is not required at all, since the fpl->list is list_add-ed at the destruction time in any case (and is unused in other code), so I propose to drop both initializations, rather than moving it after the memcpy. Please, correct me if I miss something significant. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-14[S390] cpu topology: fix lockingHeiko Carstens
cpu_coregroup_map used to grab a mutex on s390 since it was only called from process context. Since c7c22e4d5c1fdebfac4dba76de7d0338c2b0d832 "block: add support for IO CPU affinity" this is not true anymore. It now also gets called from softirq context. To prevent possible deadlocks change this in architecture code and use a spinlock instead of a mutex.
