  • Standardize the style for compiler based printf format verification.
    Standardized the location of __printf too.

    Done via script and a little typing.

    $ grep -rPl --include=*.[ch] -w "__attribute__" * | \
    grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \
    xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'

  • Moving the event counter into the dynamically allocated 'struc seq_file'
    allows poll() support without the need to allocate its own tracking
    structure.

    All current users are switched over to use the new counter.

  • Add two helpers that allow access to the seq_file's own buffer, but
    hide the internal details of seq_files.

    This allows easier implementation of special purpose filling
    functions. It also cleans up some existing functions which duplicated
    the seq_file logic.

    Make these inline functions in seq_file.h, as suggested by Al.

  • Currently seq_read assumes that the offset passed to it is always the
    offset it passed to user space. In the case pread this assumption is
    broken and we do the wrong thing when presented with pread.

    To solve this I introduce an offset cache inside of struct seq_file so we
    know where our logical file position is. Then in seq_read if we try to
    read from another offset we reset our data structures and attempt to go to
    the offset user space wanted.

  • Impact: cleanup, futureproof

    nr_cpu_ids is the (badly named) runtime limit on possible CPU numbers;
    ie. the variable version of NR_CPUS.

    With the new cpumask operators, only bits less than this are defined.
    So we should use it everywhere, rather than NR_CPUS. Eventually this
    will make it possible to allocate cpumasks of the minimal length at runtime.

  • Impact: cleanup

    seq_bitmap just calls bitmap_scnprintf on the bits: that arg can be const.
    Similarly, seq_cpumask just calls seq_bitmap.

  • Short enough reads from /proc/irq/*/smp_affinity return -EINVAL for no
    good reason.

    This became noticed with NR_CPUS=4096 patches, when length of printed
    representation of cpumask becase 1152, but cat(1) continued to read with
    1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns
    1023, check returns -EINVAL.

    Fix it by switching to seq_file, so handler will just fill buffer and
    doesn't care about offsets, length, filling EOF and all this crap.

    For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and
    seq_nodemask().

  • Add a new function:

    seq_file_root()

    This is similar to seq_path(), but calculates the path relative to the
    given root, instead of current->fs->root. If the path was unreachable
    from root, then modify the root parameter to reflect this.

  • [mszeredi@suse.cz] split big patch into managable chunks

    Add the following functions:

    dentry_path()
    seq_dentry()

    These are similar to d_path() and seq_path(). But instead of
    calculating the path within a mount namespace, they calculate the path
    from the root of the filesystem to a given dentry, ignoring mounts
    completely.

  • Fix f_version type: should be u64 instead of long

    There is a type inconsistency between struct inode i_version and struct file
    f_version.

    fs.h:

    struct inode
    u64 i_version;

    and

    struct file
    unsigned long f_version;

    Users do:

    fs/ext3/dir.c:

    if (filp->f_version != inode->i_version) {

    So why isn't f_version a u64 ? It becomes a problem if versions gets
    higher than 2^32 and we are on an architecture where longs are 32 bits.

    This patch changes the f_version type to u64, and updates the users accordingly.

    It applies to 2.6.23-rc2-mm2.

  • Many places in kernel use seq_file API to iterate over a regular list_head.
    The code for such iteration is identical in all the places, so it's worth
    introducing a common helpers.

    This makes code about 300 lines smaller:

    The first version of this patch made the helper functions static inline
    in the seq_file.h header. This patch moves them to the fs/seq_file.c as
    Andrew proposed. The vmlinux .text section sizes are as follows:

    2.6.22-rc1-mm1: 0x001794d5
    with the previous version: 0x00179505
    with this patch: 0x00179135

    The config file used was make allnoconfig with the "y" inclusion of all
    the possible options to make the files modified by the patch compile plus
    drivers I have on the test node.

    This patch:

  • 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!
