* [PATCH] futex: remove unneeded barrierRalf Baechle2006-12-07
| | | | | | | | | | | | | When disassembling a kernel I found around over 90 sync Instructions from mb, rmb and wmb calls in the kernel and only few of those make any sense to me. So here's the first one - I think the wmb() in kernel/futex.c is not needed on uniprocessors so should become an smb_wmb().

* [PATCH] generic HDLC synclink config mismatch fixPaul Fulghum2006-12-07
| | | | | | | | | | | | | | | | | Fix compile errors on mismatch between generic HDLC and synclink drivers. Notes: generic HDLC support for synclink drivers is *optional* so you can't just use depend on in Kconfig This solution is deemed the best after 7 months of review and criticism by many developers including AKPM. Read the threads on LKML before posting about this solution.

* [PATCH] remove NFSD_OPTIMIZE_SPACEAdrian Bunk2006-12-07
| | | | | | | | | | | | | | | This patch removes the unused NFSD_OPTIMIZE_SPACE. Additionally, it does differently what NFSD_OPTIMIZE_SPACE was supposed to do: Nowadays, gcc knows best when to inline code, and CONFIG_CC_OPTIMIZE_FOR_SIZE even tells gcc globally whether to optimize for size or for speed. Therefore, this patch also removes all inline's from these files.

* [PATCH] include/asm-h8300/: "extern inline" -> "static inline"Adrian Bunk2006-12-07
| | | | | | | | | | | | | | "extern inline" generates a warning with -Wmissing-prototypes and I'm currently working on getting the kernel cleaned up for adding this to the CFLAGS since it will help us to avoid a nasty class of runtime errors. If there are places that really need a forced inline, __always_inline would be the correct solution.

| | | | | | | | | | | | | | | | | | | | | | | Keith says Compiling 2.6.19-rc6 with gcc version 4.1.0 (SUSE Linux), wait_hpet_tick is optimized away to a never ending loop and the kernel hangs on boot in timer setup. 0000001a <wait_hpet_tick>: 1a: 55 push %ebp 1b: 89 e5 mov %esp,%ebp 1d: eb fe jmp 1d <wait_hpet_tick+0x3> This is not a problem with gcc 3.3.5. Adding barrier() calls to wait_hpet_tick does not help, making the variables volatile does. And the consensus is that gcc-4.1.0 is busted. Suse went and shipped gcc-4.1.0 so we cannot ban it.

* [PATCH] amba-pl010: clear error flags on rx errorLennert Buytenhek2006-12-07
| | | | | | | | | | | | | | The pl010 primecell documentation specifies that an error indicated via RSR should be cleared by a write to ECR. We didn't do this, which was causing errors to be re-reported on every call to pl010_rx_chars(). Doing a write to ECR once we detect an error appears to prevent the ep93xx console UART driver from going into a mode where it reports "ttyAM0: X input overrun(s)" every couple of keystrokes.

* [PATCH] softirq: remove BUG_ONs which can incorrectly triggerZachary Amsden2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to have tasklets get scheduled before softirqd has had a chance to spawn on all CPUs. This is totally harmless; after success during action CPU_UP_PREPARE, action CPU_ONLINE will be called, which immediately wakes softirqd on the appropriate CPU to process the already pending tasklets. So there is no danger of having a missed wakeup for any tasklets that were already pending. In particular, i386 is affected by this during startup, and is visible when using a very large initrd; during the time it takes for the initrd to be decompressed, a timer IRQ can come in and schedule RCU callbacks. It is also possible that resending of a hardware IRQ via a softirq triggers the same bug. Because of different timing conditions, this shows up in all emulators and virtual machines tested, including Xen, VMware, Virtual PC, and Qemu. It is also possible to trigger on native hardware with a large enough initrd, although I don't have a reliable case demonstrating that.

* [PATCH] autofs: fix error code path in autofs_fill_sb()Jiri Kosina2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When kernel is compiled with old version of autofs (CONFIG_AUTOFS_FS), and new (observed at least with 5.x.x) automount deamon is started, kernel correctly reports incompatible version of kernel and userland daemon, but then screws things up instead of correct handling of the error: autofs: kernel does not match daemon version ===================================== [ BUG: bad unlock balance detected! ] ------------------------------------- automount/4199 is trying to release lock (&type->s_umount_key) at: [<c0163b9e>] get_sb_nodev+0x76/0xa4 but there are no more locks to release! other info that might help us debug this: no locks held by automount/4199. stack backtrace: [<c0103b15>] dump_trace+0x68/0x1b2 [<c0103c77>] show_trace_log_lvl+0x18/0x2c [<c01041db>] show_trace+0xf/0x11 [<c010424d>] dump_stack+0x12/0x14 [<c012e02c>] print_unlock_inbalance_bug+0xe7/0xf3 [<c012fd4f>] lock_release+0x8d/0x164 [<c012b452>] up_write+0x14/0x27 [<c0163b9e>] get_sb_nodev+0x76/0xa4 [<c0163689>] vfs_kern_mount+0x83/0xf6 [<c016373e>] do_kern_mount+0x2d/0x3e [<c017513f>] do_mount+0x607/0x67a [<c0175224>] sys_mount+0x72/0xa4 [<c0102b96>] sysenter_past_esp+0x5f/0x99 DWARF2 unwinder stuck at sysenter_past_esp+0x5f/0x99 Leftover inexact backtrace: ======================= and then deadlock comes. The problem: autofs_fill_super() returns EINVAL to get_sb_nodev(), but before that, it calls kill_anon_super() to destroy the superblock which won't be needed. This is however way too soon to call kill_anon_super(), because get_sb_nodev() has to perform its own cleanup of the superblock first (deactivate_super(), etc.). The correct time to call kill_anon_super() is in the autofs_kill_sb() callback, which is called by deactivate_super() at proper time, when the superblock is ready to be killed. I can see the same faulty codepath also in autofs4. This patch solves issues in both filesystems in a same way - it postpones the kill_anon_super() until the proper time is signalized by deactivate_super() calling the kill_sb() callback.

| | | | | | | | | | | | | | | | Some people want to use ide_cd for CD-ROM but still dynamically load ide-scsi for things like tape drives. If you compile in the CD driver this works out but if you want them modular you need an option to ensure that whoever loads first the right things happen.

* [PATCH] jbd2: wait for already submitted t_sync_datalist buffer to completeHisashi Hifumi2006-12-07
| | | | | | | | | | | | | | | | | | | | | In the current jbd code, if a buffer on BJ_SyncData list is dirty and not locked, the buffer is refiled to BJ_Locked list, submitted to the IO and waited for IO completion. But the fsstress test showed the case that when a buffer was already submitted to the IO just before the buffer_dirty(bh) check, the buffer was not waited for IO completion. Following patch solves this problem. If it is assumed that a buffer is submitted to the IO before the buffer_dirty(bh) check and still being written to disk, this buffer is refiled to BJ_Locked list.

If we hit an -ENOSPC in aops->prepare_write(), we would do a truncate() to release the blocks which might have got initialized. Now the truncate would add another save link for the same inode causing a reiserfs panic for having multiple save links for the same inode. Signed-off-by: Vladimir V.

* [PATCH] sysctl: string length calculated is wrong if it contains negative ↵BP, Praveen2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | numbers In the functions do_proc_dointvec() and do_proc_doulongvec_minmax(), there seems to be a bug in string length calculation if string contains negative integer. The console log given below explains the bug. Setting negative values may not be a right thing to do for "console log level" but then the test (given below) can be used to demonstrate the bug in the code. # echo "-1 -1 -1 -123456" > /proc/sys/kernel/printk # cat /proc/sys/kernel/printk -1 -1 -1 -1234 # # echo "-1 -1 -1 123456" > /proc/sys/kernel/printk # cat /proc/sys/kernel/printk -1 -1 -1 1234 # (akpm: the bug is that 123456 gets truncated) It works as expected if string contains all +ve integers # echo "1 2 3 4" > /proc/sys/kernel/printk # cat /proc/sys/kernel/printk 1 2 3 4 # The patch given below fixes the issue.
