  • 4a7b4d236   x86: pageattr-test: remove srandom32 call ... Browse Code »

    pageattr-test calls srandom32() once every test iteration. But calling
    srandom32() after late_initcalls is not meaningfull. Because the random
    states for random32() is mixed by good random numbers in late_initcall
    prandom_reseed().

    So this removes the call to srandom32().

  • 3e6628c4b   idr: introduce idr_alloc_cyclic() ... Browse Code »

    As Tejun points out, there are several users of the IDR facility that
    attempt to use it in a cyclic fashion. These users are likely to see
    -ENOSPC errors after the counter wraps one or more times however.

    This patchset adds a new idr_alloc_cyclic routine and converts several
    of these users to it. Many of these users are in obscure parts of the
    kernel, and I don't have a good way to test some of them. The change is
    pretty straightforward though, so hopefully it won't be an issue.

    There is one other cyclic user of idr_alloc that I didn't touch in
    ipc/util.c. That one is doing some strange stuff that I didn't quite
    understand, but it looks like it should probably be converted later
    somehow.

    This patch:

    Thus spake Tejun Heo:

    Ooh, BTW, the cyclic allocation is broken. It's prone to -ENOSPC
    after the first wraparound. There are several cyclic users in the
    kernel and I think it probably would be best to implement cyclic
    support in idr.

    This patch does that by adding new idr_alloc_cyclic function that such
    users in the kernel can use. With this, there's no need for a caller to
    keep track of the last value used as that's now tracked internally. This
    should prevent the ENOSPC problems that can hit when the "last allocated"
    counter exceeds INT_MAX.

    Later patches will convert existing cyclic users to the new interface.

  • f1e6fb0ab   fat (exportfs): rebuild directory-inode if fat_dget() ... Browse Code »

    This patch enables rebuilding of directory inodes which are not present in
    the cache.This is done by traversing the disk clusters to find the
    directory entry of the parent directory and using its i_pos to build the
    inode.

    The traversal is done by fat_scan_logstart() which is similar to
    fat_scan() but matches i_pos values instead of names.fat_scan_logstart()
    needs an inode parameter to work, for which a dummy inode is created by
    it's caller fat_rebuild_parent(). This dummy inode is destroyed after the
    traversal completes.

    All this is done only if the nostale_ro nfs mount option is specified.

    If the cache lookups fail,use the i_pos value to find the directory entry
    of the inode and rebuild the inode.Since this involves accessing the FAT

  • ea3983ace   fat: restructure export_operations ... Browse Code »

    Define two nfs export_operation structures,one for 'stale_rw' mounts and
    the other for 'nostale_ro'. The latter uses i_pos as a basis for encoding
    and decoding file handles.

    Also, assign i_pos to kstat->ino. The logic for rebuilding the inode is
    added in the subsequent patches.

  • 2628b7a6a   fat: introduce 2 new values for the -o nfs mount option ... Browse Code »

    This patchset eliminates the client side ESTALE errors when a FAT
    partition exported over NFS has its dentries evicted from the cache. The
    idea is to find the on-disk location_'i_pos' of the dirent of the inode
    that has been evicted and use it to rebuild the inode.

    This patch:

    Provide two possible values 'stale_rw' and 'nostale_ro' for the -o nfs
    mount option.The first one allows all file operations but does not reduce
    ESTALE errors on memory constrained systems. The second one eliminates
    ESTALE errors but mounts the filesystem as read-only. Not specifying a
    value defaults to 'stale_rw'.

    driver, so this looks like a copy-paste bug.
