  • 9a311b96c   hpfs: remove the BKL ... Browse Code »

    This removes the BKL in hpfs in a rather awful
    way, by making the code only work on uniprocessor
    systems without kernel preemption, as suggested
    by Andi Kleen.

    The HPFS code probably has close to zero remaining
    users on current kernels, all archeological uses of
    the file system can probably be done with the significant
    restrictions.

    The hpfs_lock/hpfs_unlock functions are left in the
    code, sincen Mikulas has indicated that he is still
    interested in fixing it in a better way.

  • 274052ef0   hpfs_setattr error case avoids unlock_kernel ... Browse Code »

    This fixed a case that 'sparse' spotted where hpfs_setattr has an error return
    that didn't go through it's path that unlocks.

    This is against git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
    version 6313e3c21743cc88bb5bd8aa72948ee1e83937b6.

    Build tested only, I don't have an hpfs file system to test.

  • 1025774ce   remove inode_setattr ... Browse Code »

    Replace inode_setattr with opencoded variants of it in all callers. This
    moves the remaining call to vmtruncate into the filesystem methods where it
    can be replaced with the proper truncate sequence.

    In a few cases it was obvious that we would never end up calling vmtruncate
    so it was left out in the opencoded variant:

    spufs: explicitly checks for ATTR_SIZE earlier
    btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier
    ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above

    In addition to that ncpfs called inode_setattr with handcrafted iattrs,
    which allowed to trim down the opencoded variant.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 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)

  • ba52de123   [PATCH] inode-diet: Eliminate i_blksize from the inode structure ... Browse Code »

    This eliminates the i_blksize field from struct inode. Filesystems that want
    to provide a per-inode st_blksize can do so by providing their own getattr
    routine instead of using the generic_fillattr() function.

    Note that some filesystems were providing pretty much random (and incorrect)
    values for i_blksize.

  • fef266580   [PATCH] update filesystems for new delete_inode behavior ... Browse Code »

    Update the file systems in fs/ implementing a delete_inode() callback to
    call truncate_inode_pages(). One implementation note: In developing this
    patch I put the calls to truncate_inode_pages() at the very top of those
    filesystems delete_inode() callbacks in order to retain the previous
    behavior. I'm guessing that some of those could probably be optimized.

    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!
