2009-10-11headers: remove sched.h from interrupt.hAlexey Dobriyan145-1/+145
After m68k's task_thread_info() doesn't refer to current, it's possible to remove sched.h from interrupt.h and not break m68k! Many thanks to Heiko Carstens for allowing this. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

2009-10-09IRQ: Change __softirq_pending to unsigned int in asm-generic/hardirq.h.Ralf Baechle1-1/+1
Since the beginnings in aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d ("asm-generic: add generic versions of common headers") the generic version of <asm/hardirq.h> defined __softirq_pending as unsigned long. Which is different from other architectures for no apparent good reason and was causing the following warning: kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick': kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int' Reported and initial patch by Wu Zhangjin <wuzhangjin@gmail.com>. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Acked-by: Arnd Bergmann <arnd@arndb.de> [ Arnd points out that we really should make sure parisc and alpha are ok with this, since they have also been converted to use the generic hardirq.h file. But neither seems to use it, although parisc does build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also appears unused.. - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-10-09sh: Don't allocate smaller sized mappings on every iterationMatt Fleming1-0/+7
Currently, we've got the less than ideal situation where if we need to allocate a 256MB mapping we'll allocate four entries like so, entry 1: 128MB entry 2: 64MB entry 3: 16MB entry 4: 16MB This is because as we execute the loop in pmb_remap() we will progressively try mapping the remaining address space with smaller and smaller sizes. This isn't good because the size we use on one iteration may be the perfect size to use on the next iteration, for instance when the initial size is divisible by one of the PMB mapping sizes. With this patch, we now only need two entries in the PMB to map 256MB of address space, entry 1: 128MB entry 2: 128MB Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-08fix readahead calculations in xfs_dir2_leaf_getdents()Eric Sandeen1-1/+3
This is for bug #850, http://oss.sgi.com/bugzilla/show_bug.cgi?id=850 XFS file system segfaults , repeatedly and 100% reproducable in 2.6.30 , 2.6.31 The above only showed up on a CONFIG_XFS_DEBUG=y kernel, because xfs_bmapi() ASSERTs that it has been asked for at least one map, and it was getting 0. The root cause is that our guesstimated "bufsize" from xfs_file_readdir was fairly small, and the bufsize -= length; in the loop was going negative - except bufsize is a size_t, so it was wrapping to a very large number. Then when we did ra_want = howmany(bufsize + mp->m_dirblksize, mp->m_sb.sb_blocksize) - 1; with that very large number, the (int) ra_want was coming out negative, and a subsequent compare: if (1 + ra_want > map_blocks ... was coming out -true- (negative int compare w/ uint) and we went back to xfs_bmapi() for more, even though we did not need more, and asked for 0 maps, and hit the ASSERT. We have kind of a type mess here, but just keeping bufsize from going negative is probably sufficient to avoid the problem.

2009-10-08xfs: make sure xfs_sync_fsdata covers the logDave Chinner1-7/+21
We want to always cover the log after writing out the superblock, and in case of a synchronous writeout make sure we actually wait for the log to be covered. That way a filesystem that has been sync()ed can be considered clean by log recovery.

2009-10-08xfs: cleanup ->sync_fsChristoph Hellwig1-18/+18
Sort out ->sync_fs to not perform a superblock writeback for the wait = 0 case as that is just an optional first pass and the superblock will be written back properly in the next call with wait = 1. Instead perform an opportunistic quota writeback to have less work later. Also remove the freeze special case as we do a proper wait = 1 call in the freeze code anyway. Also rename the function to xfs_fs_sync_fs to match the normal naming convention, update comments and avoid calling into the laptop_mode logic on an error.

2009-10-08xfs: fix xfs_quiesce_dataDave Chinner1-3/+5
We need to do a synchronous xfs_sync_fsdata to make sure the superblock actually is on disk when we return. Also remove SYNC_BDFLUSH flag to xfs_sync_inodes because that particular flag is never checked. Move xfs_filestream_flush call later to only release inodes after they have been written out.

2009-10-08xfs: implement ->dirty_inode to fix timestamp handlingChristoph Hellwig10-56/+70
This is picking up on Felix's repost of Dave's patch to implement a .dirty_inode method. We really need this notification because the VFS keeps writing directly into the inode structure instead of going through methods to update this state. In addition to the long-known atime issue we now also have a caller in VM code that updates c/mtime that way for shared writeable mmaps. And I found another one that no one has noticed in practice in the FIFO code. So implement ->dirty_inode to set i_update_core whenever the inode gets externally dirtied, and switch the c/mtime handling to the same scheme we already use for atime (always picking up the value from the Linux inode). Note that this patch also removes the xfs_synchronize_atime call in xfs_reclaim it was superflous as we already synchronize the time when writing the inode via the log (xfs_inode_item_format) or the normal buffers (xfs_iflush_int). In addition also remove the I_CLEAR check before copying the Linux timestamps - now that we always have the Linux inode available we can always use the timestamps in it. Also switch to just using file_update_time for regular reads/writes - that will get us all optimization done to it for free and make sure we notice early when it breaks.

2009-10-08NFSv4: Kill nfs4_renewd_prepare_shutdown()Trond Myklebust2-7/+0
The NFSv4 renew daemon is shared between all active super blocks that refer to a particular NFS server, so it is wrong to be shutting it down in nfs4_kill_super every time a super block is destroyed. This patch therefore kills nfs4_renewd_prepare_shutdown altogether, and leaves it up to nfs4_shutdown_client() to also shut down the renew daemon by means of the existing call to nfs4_kill_renewd().

2009-10-08x86, timers: Check for pending timers after (device) interruptsArjan van de Ven2-0/+3
Now that range timers and deferred timers are common, I found a problem with these using the "perf timechart" tool. Frans Pop also reported high scheduler latencies via LatencyTop, when using iwlagn. It turns out that on x86, these two 'opportunistic' timers only get checked when another "real" timer happens. These opportunistic timers have the objective to save power by hitchhiking on other wakeups, as to avoid CPU wakeups by themselves as much as possible. The change in this patch runs this check not only at timer interrupts, but at all (device) interrupts. The effect is that: 1) the deferred timers/range timers get delayed less 2) the range timers cause less wakeups by themselves because the percentage of hitchhiking on existing wakeup events goes up. I've verified the working of the patch using "perf timechart", the original exposed bug is gone with this patch. Frans also reported success - the latencies are now down in the expected ~10 msec range.
