  • 788257d61   ufs: remove the BKL ... Browse Code »

    This introduces a new per-superblock mutex in UFS to replace
    the big kernel lock. I have been careful to avoid nested
    calls to lock_ufs and to get the lock order right with
    respect to other mutexes, in particular lock_super.

    I did not make any attempt to prove that the big kernel
    lock is not needed in a particular place in the code,
    which is very possible.

    The mutex has a significant performance impact, so it is only
    used on SMP or PREEMPT configurations.

    As Nick Piggin noticed, any allocation inside of the lock
    may end up deadlocking when we get to ufs_getfrag_block
    in the reclaim task, so we now use GFP_NOFS.

  • 8f45c33de   ufs: Remove dead quota code ... Browse Code »

    UFS quota is non-functional at least since 2.6.12 because dq_op was set
    to NULL. Since the filesystem exists mainly to allow cooperation with Solaris
    and quota format isn't standard, just remove the dead code.

  • 871a29315   dquot: cleanup dquot initialize routine ... Browse Code »

    Get rid of the initialize dquot operation - it is now always called from
    the filesystem and if a filesystem really needs it's own (which none
    currently does) it can just call into it's own routine directly.

    Rename the now static low-level dquot_initialize helper to __dquot_initialize
    and vfs_dq_init to dquot_initialize to have a consistent namespace.

  • 907f4554e   dquot: move dquot initialization responsibility into the filesystem ... Browse Code »

    Currently various places in the VFS call vfs_dq_init directly. This means
    we tie the quota code into the VFS. Get rid of that and make the
    filesystem responsible for the initialization. For most metadata operations
    this is a straight forward move into the methods, but for truncate and
    open it's a bit more complicated.

    For truncate we currently only call vfs_dq_init for the sys_truncate case
    because open already takes care of it for ftruncate and open(O_TRUNC) - the
    new code causes an additional vfs_dq_init for those which is harmless.

    For open the initialization is moved from do_filp_open into the open method,
    which means it happens slightly earlier now, and only for regular files.
    The latter is fine because we don't need to initialize it for operations
    on special files, and we already do it as part of the namespace operations
    for directories.

    Add a dquot_file_open helper that filesystems that support generic quotas
    can use to fill in ->open.

  • 723be1f30   ufs: copy symlink data into the correct union member ... Browse Code »

    Copy symlink data into the union member it is accessed through. Although
    this shouldn't make a difference to behaviour it makes the code easier
    to follow and grep through. It may also prevent problems if the
    struct/union definitions change in the future.

  • e54205988   drop linux/ufs_fs.h from userspace export and relocate it to fs/ufs/ufs_fs.h ... Browse Code »

    Per previous discussions about cleaning up ufs_fs.h, people just want
    this straight up dropped from userspace export. The only remaining
    consumer (silo) has been fixed a while ago to not rely on this header.
    This allows use to move it completely from include/linux/ to fs/ufs/
    seeing as how the only in-kernel consumer is fs/ufs/.

  • b55c460da   iget: stop UFS from using iget() and read_inode() ... Browse Code »

    Stop the UFS filesystem from using iget() and read_inode(). Replace
    ufs_read_inode() with ufs_iget(), and call that instead of iget(). ufs_iget()
    then uses iget_locked() directly and returns a proper error code instead of an
    inode in the event of an error.

    ufs_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

  • bcd6d4ecf   ufs: move non-layout parts of ufs_fs.h to fs/ufs/ ... Browse Code »

    Move prototypes and in-core structures to fs/ufs/ similar to what most
    other filesystems already do.

    I made little modifications: move also ufs debug macros and
    mount options constants into fs/ufs/ufs.h, this stuff
    also private for ufs.

  • c5ef1c42c   [PATCH] mark struct inode_operations const 3 ... Browse Code »

    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.

  • 9a53c3a78   [PATCH] r/o bind mounts: unlink: monitor i_nlink ... Browse Code »

    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.

  • abf5d15fd   [PATCH] ufs: easy debug ... Browse Code »

    Currently to turn on debug mode "user" has to edit ~10 files, to turn off he
    has to do it again.

    This patch introduce such changes:
    1)turn on(off) debug messages via ".config"
    2)remove unnecessary duplication of code
    3)make "UFSD" macros more similar to function
    4)fix some compiler warnings

    This series of patches finished "bugs fixing" mentioned
    here http://lkml.org/lkml/2006/1/31/275 .

    The main bugs:
    * for i in `seq 1 1000`; do touch $i; done - crash system
    * mkdir create directory without "." and ".." entries

    The suggested solution is work with page cache instead of straight work
    with blocks. Such solution has following advantages

    * reduce code size and its complexity
    * some global locks go away
    * fix bugs

    The most part of code is stolen from ext2, because of it has similar
    directory structure.

    Patches testes with UFS1 and UFS2 file systems.

    This patch installs i_mapping->a_ops for directory inodes and removes some
    duplicated code.

    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!
