  • 9f58d3503   UBIFS: add a superblock flag for free space fix-up ... Browse Code »

    The 'space_fixup' flag can be set in the superblock of a new filesystem by
    mkfs.ubifs to indicate that any eraseblocks with free space remaining should be
    fixed-up the first time it's mounted (after which the flag is un-set). This
    means that the UBIFS image has been flashed by a "dumb" flasher and the free
    space has been actually programmed (writing all 0xFFs), so this free space
    cannot be used. UBIFS fixes the free space up by re-writing the contents of all
    LEBs with free space using the atomic LEB change UBI operation.

    Artem: improved commit message, add some more commentaries to the code.

  • cc64f774b   UBIFS: use __packed instead of __attribute__((packed)) ... Browse Code »

    There was an attempt to standartize various "__attribute__" and
    other macros in order to have potentially portable and more
    consistent code, see commit 82ddcb040570411fc2d421d96b3e69711c670328.

    Note, that commit refers Rober Love's blog post, but the URL
    is broken, the valid URL is:
    http://blog.rlove.org/2005/10/with-little-help-from-your-compiler.html

    Moreover, nowadays checkpatch.pl warns about using
    __attribute__((packed)):

    "WARNING: __packed is preferred over __attribute__((packed))"

    It is not a big deal for UBIFS to use __packed, so let's do it.

  • 963f0cf6d   UBIFS: add R/O compatibility ... Browse Code »

    Now UBIFS is supported by u-boot. If we ever decide to change the
    media format, then people will have to upgrade their u-boots to
    mount new format images. However, very often it is possible to
    preserve R/O forward-compatibility, even though the write
    forward-compatibility is not preserved.

    This patch introduces a new super-block field which stores the
    R/O compatibility version.

  • b364b41ae   UBIFS: reserve more space for index ... Browse Code »

    At the moment UBIFS reserves twice old index size space for the
    index. But this is not enough in some cases, because if the indexing
    node are very fragmented and there are many small gaps, while the
    dirty index has big znodes - in-the-gaps method would fail.

    Thus, reserve trise as more, in which case we are guaranteed that
    we can commit in any case.
