  • 4e34e719e   fs: take the ACL checks to common code ... Browse Code »

    Replace the ->check_acl method with a ->get_acl method that simply reads an
    ACL from disk after having a cache miss. This means we can replace the ACL
    checking boilerplate code with a single implementation in namei.c.

  • 02c24a821   fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers ... Browse Code »

    Btrfs needs to be able to control how filemap_write_and_wait_range() is called
    in fsync to make it less of a painful operation, so push down taking i_mutex and
    the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some
    file systems can drop taking the i_mutex altogether it seems, like ext3 and
    ocfs2. For correctness sake I just pushed everything down in all cases to make
    sure that we keep the current behavior the same for everybody, and then each
    individual fs maintainer can make up their mind about what to do from there.
    Thanks,

  • dd3932edd   block: remove BLKDEV_IFL_WAIT ... Browse Code »

    All the blkdev_issue_* helpers can only sanely be used for synchronous
    caller. To issue cache flushes or barriers asynchronously the caller needs
    to set up a bio by itself with a completion callback to move the asynchronous
    state machine ahead. So drop the BLKDEV_IFL_WAIT flag that is always
    specified when calling blkdev_issue_* and also remove the now unused flags
    argument to blkdev_issue_flush and blkdev_issue_zeroout. For
    blkdev_issue_discard we need to keep it for the secure discard flag, which
    gains a more descriptive name and loses the bitops vs flag confusion.

    a) count file openers correctly; i_count use was completely wrong
    b) use new mutex for exclusion between final close/open/truncate,
    to protect tailpacking logics. i_mutex use was wrong and resulted
    in deadlocks.

  • 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.

  • 45b03d5e8   reiserfs: rework reiserfs_warning ... Browse Code »

    ReiserFS warnings can be somewhat inconsistent.
    In some cases:
    * a unique identifier may be associated with it
    * the function name may be included
    * the device may be printed separately

    This patch aims to make warnings more consistent. reiserfs_warning() prints
    the device name, so printing it a second time is not required. The function
    name for a warning is always helpful in debugging, so it is now automatically
    inserted into the output. Hans has stated that every warning should have
    a unique identifier. Some cases lack them, others really shouldn't have them.
    reiserfs_warning() now expects an id associated with each message. In the
    rare case where one isn't needed, "" will suffice.

    Some users have been having problems with utilities like cp or dd dumping
    core when they try to copy a file that's too large for the destination
    filesystem (typically, > 4gb). Apparently, some defunct standards required
    SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it
    for when a written file exceeds the process's resource limits. I'd like to
    limit SIGXFSZs to the bare minimum required by SUS.

  • 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.

  • de14569f9   [PATCH] resierfs: avoid tail packing if an inode was ever mmapped ... Browse Code »

    This patch fixes a confusion reiserfs has for a long time.

    On release file operation reiserfs used to try to pack file data stored in
    last incomplete page of some files into metadata blocks. After packing the
    page got cleared with clear_page_dirty. It did not take into account that
    the page may be mmaped into other process's address space. Recent
    replacement for clear_page_dirty cancel_dirty_page found the confusion with
    sanity check that page has to be not mapped.

    The patch fixes the confusion by making reiserfs avoid tail packing if an
    inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are
    serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the
    mutex and sets a bit in reiserfs specific inode flags.
    reiserfs_file_release checks the bit having the mutex locked. If bit is
    set - tail packing is avoided. This eliminates a possibility that mmapped
    page gets cancel_page_dirty-ed.

    We add a save link for O_DIRECT writes to protect the i_size against the
    crashes before we actually finish the I/O. If we hit an -ENOSPC in
    aops->prepare_write(), we would do a truncate() to release the blocks which
    might have got initialized. Now the truncate would add another save link
    for the same inode causing a reiserfs panic for having multiple save links
    for the same inode.

  • 73ce5934e   [PATCH] reiserfs: fix journaling issue regarding fsync() ... Browse Code »

    When write() extends a file(i_size is increased) and fsync() is called,
    change of inode must be written to journaling area through fsync().
    But,currently the i_trans_id is not correctly updated when i_size is
    increased. So fsync() does not kick the journal writer.

    Reiserfs_file_write() already updates the transaction when blocks are
    allocated, but the case when i_size increases and new blocks are not added
    is not correctly treated.

    Following patch fix this bug.

  • 5274f052e   [PATCH] Introduce sys_splice() system call ... Browse Code »

    This adds support for the sys_splice system call. Using a pipe as a
    transport, it can connect to files or sockets (latter as output only).

    From the splice.c comments:

    "splice": joining two ropes together by interweaving their strands.

    This is the "extended pipe" functionality, where a pipe is used as
    an arbitrary in-memory buffer. Think of a pipe as a small kernel
    buffer that you can use to transfer data from one end to the other.

    The traditional unix read/write is extended with a "splice()" operation
    that transfers data buffers to or from a pipe buffer.

    Named by Larry McVoy, original implementation from Linus, extended by
    Jens to support splicing to files and fixing the initial implementation
    bugs.

    This is a conversion to make the various file_operations structs in fs/

    The goal is both to increase correctness (harder to accidentally write to
    shared datastructures) and reducing the false sharing of cachelines with
    things that get dirty in .data (while .rodata is nicely read only and thus
    cache clean)
