  • 441c793a5   net: cleanup unused macros in net directory ... Browse Code »

    Clean up some unused macros in net/*.
    1. be left for code change. e.g. PGV_FROM_VMALLOC, PGV_FROM_VMALLOC, KMEM_SAFETYZONE.
    2. never be used since introduced to kernel.
    e.g. P9_RDMA_MAX_SGE, UTIL_CTRL_PKT_SIZE.

  • 15fd0cd9a   net: autoconvert trivial BKL users to private mutex ... Browse Code »

    All these files use the big kernel lock in a trivial
    way to serialize their private file operations,
    typically resulting from an earlier semi-automatic
    pushdown from VFS.

    None of these drivers appears to want to lock against
    other code, and they all use the BKL as the top-level
    lock in their file operations, meaning that there
    is no lock-order inversion problem.

    Consequently, we can remove the BKL completely,
    replacing it with a per-file mutex in every case.
    Using a scripted approach means we can avoid
    typos.

    file=$1
    name=$2
    if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
    sed -i '/include.*/d' ${file}
    else
    sed -i 's/include.*.*$/include /g' ${file}
    fi
    sed -i ${file} \
    -e "/^#include.*linux.mutex.h/,$ {
    1,/^\(static\|int\|long\)/ {
    /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);

    } }" \
    -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
    -e '/[ ]*cycle_kernel_lock();/d'
    else
    sed -i -e '/include.*\/d' ${file} \
    -e '/cycle_kernel_lock()/d'
    fi

  • 405f55712   headers: smp_lock.h redux ... Browse Code »

    * Remove smp_lock.h from files which don't need it (including some headers!)
    * Add smp_lock.h to files which do need it
    * Make smp_lock.h include conditional in hardirq.h
    It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

    This will make hardirq.h inclusion cheaper for every PREEMPT=n config
    (which includes allmodconfig/allyesconfig, BTW)

  • e49332bd1   [PATCH] misc verify_area cleanups ... Browse Code »

    There were still a few comments left refering to verify_area, and two
    functions, verify_area_skas & verify_area_tt that just wrap corresponding
    access_ok_skas & access_ok_tt functions, just like verify_area does for
    access_ok - deprecate those.

    There was also a few places that still used verify_area in commented-out
    code, fix those up to use access_ok.

    After applying this one there should not be anything left but finally
    removing verify_area completely, which will happen after a kernel release
    or two.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
