  • 681142f92   fat: make discard a mount option ... Browse Code »

    Currently shipping discard capable SSDs and arrays have rather sub-optimal
    implementations of the command and can the use of it can cause massive
    slowdowns. Make issueing these commands option as it's already in btrfs
    and gfs2.

    * mark directory data blocks as assoc. metadata
    * add new inode to deal with FAT, mark FAT blocks as assoc. metadata of that
    * now ->fsync() is trivial both for files and directories

  • 85c785919   FAT: add 'errors' mount option ... Browse Code »

    On severe errors FAT remounts itself in read-only mode. Allow to
    specify FAT fs desired behavior through 'errors' mount option:
    panic, continue or remount read-only.

    `mount -t [fat|vfat] -o errors=[panic,remount-ro,continue] \
    `

    This is analog to ext2 fs 'errors' mount option.

  • 606e423e4   fat: Update free_clusters even if it is untrusted ... Browse Code »

    Currently, free_clusters is not updated until it is trusted, because
    Windows doesn't update it correctly.

    But if user is using FAT driver of Linux, it updates free_clusters
    correctly. Instead, this updates it even if it's untrusted, so if
    free_clustes is correct, now keep correct value.

  • 9f966be89   fat: optimize fat_count_free_clusters() ... Browse Code »

    On large partition, scanning the free clusters is very slow if users
    doesn't use "usefree" option.

    For optimizing it, this patch uses sb_breadahead() to read of FAT
    sectors. On some user's 15GB partition, this patch improved it very
    much (1min => 600ms).

    The following is the result of 2GB partition on my machine.

    without patch:
    root@devron (/)# time df -h > /dev/null

    real 0m1.202s
    user 0m0.000s
    sys 0m0.440s

    with patch:
    root@devron (/)# time df -h > /dev/null

    real 0m0.378s
    user 0m0.012s
    sys 0m0.168s

  • 98283bb49   fat: Fix the race of read/write the FAT12 entry ... Browse Code »

    FAT12 entry is 12bits, so it needs 2 phase to update the value. And
    writer and reader access it without any lock, so reader can get the
    half updated value.

    This fixes the long standing race condition by adding a global
    spinlock to only FAT12 for avoiding any impact against FAT16/32.

    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!
