  • First thing mm.h does is including sched.h solely for can_do_mlock() inline
    function which has "current" dereference inside. By dealing with can_do_mlock()
    mm.h can be detached from sched.h which is good. See below, why.

    This patch
    a) removes unconditional inclusion of sched.h from mm.h
    b) makes can_do_mlock() normal function in mm/mlock.c
    c) exports can_do_mlock() to not break compilation
    d) adds sched.h inclusions back to files that were getting it indirectly.
    e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
    getting them indirectly

    Net result is:
    a) mm.h users would get less code to open, read, preprocess, parse, ... if
    they don't need sched.h
    b) sched.h stops being dependency for significant number of files:
    on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
    after patch it's only 3744 (-8.3%).

    Cross-compile tested on

    all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
    alpha alpha-up
    arm
    i386 i386-up i386-defconfig i386-allnoconfig
    ia64 ia64-up
    m68k
    mips
    parisc parisc-up
    powerpc powerpc-up
    s390 s390-up
    sparc sparc-up
    sparc64 sparc64-up
    um-x86_64
    x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

    as well as my two usual configs.

  • Make UDF use get_bh() instead of directly accessing b_count and use
    brelse() instead of udf_release_data() which does just brelse()...

  • Use sector_t and loff_t for file offsets in UDF filesystem. Otherwise an
    overflow may occur for long files. Also make inode_bmap() return offset in
    the extent in number of blocks instead of number of bytes - for most
    callers this is more convenient.

  • It appears that a minor thinko occurred in udf_rmdir and the
    (already-cleared) link count on the directory that is being removed was
    being decremented instead of the link count on its parent directory. This
    gives rise to lots of kernel messages similar to:

    UDF-fs warning (device loop1): udf_rmdir: empty directory has nlink != 2 (8)

    when removing directory trees. No other ill effects have been observed but
    I guess it could theoretically result in the link count overflowing on a
    very long-lived, much modified directory.

  • Many struct inode_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • Some filesystems, instead of simply decrementing i_nlink, simply zero it
    during an unlink operation. We need to catch these in addition to the
    decrement operations.

  • This is mostly included for parity with dec_nlink(), where we will have some
    more hooks. This one should stay pretty darn straightforward for now.

  • When a filesystem decrements i_nlink to zero, it means that a write must be
    performed in order to drop the inode from the filesystem.

    We're shortly going to have keep filesystems from being remounted r/o between
    the time that this i_nlink decrement and that write occurs.

    So, add a little helper function to do the decrements. We'll tie into it in a
    bit to note when i_nlink hits zero.

  • 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!
