Make sure that a bio doesn't contain NULL pages in the front of its vec, if a device bounces a bio that doesn't start from 0. Problem noted by Mark Haverkamp. Signed-off-by:

The new pipe buffer merging doesn't check for the "no readers" case, so with small writes that coalesce, we may not get a timely SIGPIPE/EPIPE notification to the writer. Signed-off-by:

The pipe code has traditionally not cared about which end-point of the pipe you are polling, meaning that if you poll the write-only end of a pipe, it will still set the "this pipe is readable" bits if there is data to be read on the read side. That makes no sense, and together with the new bigger buffers breaks python-twisted. Based on debugging/patch by Andrea Arcangeli and testcase from Thomas Crhak

srat's node_to_pxm() references pxm2node[] after init. so pxm2node[] should not be __initdata. Error: ./arch/x86_64/mm/srat.o .text refers to 0000000000000008 R_X86_64_32S .init.data Error: ./arch/x86_64/mm/srat.o .text refers to 0000000000000015 R_X86_64_32S .init.data Signed-off-by:

Spotted by itkes@fat.imed.msu.ru, the fn_hash_dump_bucket() main loop does not increment 'i' properly, and thus routes will not be listed, when the test 'i < s_i' passes. The bug was added when the code was converted over to hlist_for_each_entry() by your's truly. Signed-off-by:

setup_APIC_timer is only called in __init context and uses __initdata

wait_timer_tick refers to the __init functions wait_8254_wraparound or wait_hpet_tick, hence must be __initdata.

I have just tested kernel version 2.6.11-rc5 and noticed it is not possible to do an USB transfer by submitting an URB to an output endpoint. This breaks newest versions of libusb and thus SANE, gphoto2, and a lot of software. The bug was introduced in version 2.6.11-rc1 and is due to a wrong comparison. Signed-off-by:

The attached patch makes keyctl() use the correct argument when invoking the KEYCTL_JOIN_SESSION_KEYRING function. I'm not sure how this evaded testing before, but I suspect the compiler was kind and made both argument registers hold the same value. Thanks to Kevin Coffman <kwc@citi.umich.edu> for spotting this.

This fixes a potentially bad (although very rarely triggered) bug in the ppc64 hugepage code. hpte_update() did not correctly calculate the address for hugepages, so pte_clear() (which we use for hugepage ptes as well as normal ones) would not correctly flush the hash page table entry. Under the right circumstances this could potentially lead to duplicate hash entries, which is very bad. davem's upcoming patch to pass the virtual address directly to set_pte() and its ilk will obsolete this, but this is bad enough it should probably be fixed in the meantime.

This is the best we've got: We cannot release and re-grab lock, since checkentry() is called before ip_tables.c grabs ipt_mutex. We also cannot grab the hashtable spinlock, since htable_create will call vmalloc, and that can sleep. And we cannot just re-search the list of htable's in htable_create(), since then we would create duplicate proc files. Signed-off-by:

IRQ races during change of mtu - NAPI poll must be enabled prior to IRQ activation or the IRQ handler will not know what to do with an incoming packet; - rtl8169_down() needs to try twice to sync with the IRQ handler when it is not issued under !netif_running() protection. Both changes make it safe to request a change of mtu on a live device. Signed-off-by:

Some futex functions do get_user calls while holding mmap_sem for reading. If get_user() faults, and another thread happens to be in mmap (or somewhere else holding waiting on down_write for the same semaphore), then do_page_fault will deadlock. Most architectures seem to be exposed to this. To avoid it, make sure the page is available. If not, release the semaphore, fault it in and retry. I also found another exposure by inspection, moving some of the code around avoids the possible deadlock there. Signed-off-by:
