Allow nbd to expose the nbd-client daemon's PID in /sys/block/nbd<x>/pid. This is helpful for tracking connection status of a device and for determining which nbd devices are currently in use. Signed-off-by:

Sometimes the kernel prints something interesting while userspace bootup keeps messages turned off via loglevel. Enable the printing of /all/ kernel messages via the "ignore_loglevel" boot option. Off by default. Signed-off-by:

The hash_lock must only ever be taken with irqs disabled. This happens in all the important places, except one codepath: register_lock_class(). The race should trigger rarely because register_lock_class() is quite rare and single-threaded (happens during init most of the time). The fix is to disable irqs. ( bug found live in -rt: there preemption is alot more agressive and preempting with the hash-lock held caused a lockup.) Signed-off-by:

Remove the ki_retried member from struct kiocb. I think the idea was bounced around a while back, but Arnaldo pointed out another reason that we should dig it up when he pointed out that the last cacheline of struct kiocb only contains 4 bytes. By removing the debugging member, we save more than the 8 byte on 64 bit machines. Signed-off-by:

io_submit_one assigns ki_left = ki_nbytes = iocb->aio_nbytes, then calls down to aio_setup_iocb, then to aio_setup_single_vector. In there, ki_nbytes is reassigned to the same value it got two call stack above it. There is no need to do so. Signed-off-by:

The elf note saving code is currently duplicated over several architectures. This cleanup patch simply adds code to a common file and then replaces the arch-specific code with calls to the newly added code. The only drawback with this approach is that s390 doesn't fully support kexec-on-panic which for that arch leads to introduction of unused code. Signed-off-by:

Make the contents of the userspace asm/setup.h header consistent on all architectures: - export setup.h to userspace on all architectures - export only COMMAND_LINE_SIZE to userspace - frv: move COMMAND_LINE_SIZE from param.h - i386: remove duplicate COMMAND_LINE_SIZE from param.h - arm: - export ATAGs to userspace - change u8/u16/u32 to __u8/__u16/__u32 Signed-off-by:

Twenty characters in cp936 are not correctly handled. They're all in the U00 plane. nls_cp936 converts all U00XY to XY but this is not correct for some characters.(e.g. U00B7 -> A1A4, U00A8 -> A1A7). This problem is fixed by generating u2c_00 based on all c2u_xx and changing uni2char() to give U00 plane a special handling. The "â¬"(U20AC,80 in cp936) is also be handled properly. Acked-by:

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(). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

"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. Signed-off-by:

If you do something like: # touch foo # tail -f foo & # rm foo # <take snapshot> # <mount snapshot> you'll panic, because ext3/4 tries to do orphan list processing on the readonly snapshot device, and: kernel: journal commit I/O error kernel: Assertion failure in journal_flush_Rsmp_e2f189ce() at journal.c:1356: "!journal->j_checkpoint_transactions" kernel: Kernel panic: Fatal exception for a truly readonly underlying device, it's reasonable and necessary to just skip orphan list processing.

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.

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.
