Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-arm64-arm64-examine      6 reboot                   fail REGR. vs. 110515
 build-i386-pvops              5 kernel-build             fail REGR. vs. 110515
 test-amd64-amd64-xl-qemut-win7-amd64 15 guest-localmigrate/x10 fail REGR. vs. 
 build-armhf-pvops             5 kernel-build             fail REGR. vs. 110515

Regressions which are regarded as allowable (not blocking):
 test-amd64-amd64-rumprun-amd64 16 rumprun-demo-xenstorels/xenstorels.repeat 
fail REGR. vs. 110515

    Hang/soft lockup in d_invalidate with simultaneous calls
    It's not hard to trigger a bunch of d_invalidate() on the same
    dentry in parallel.  They end up fighting each other - any
    dentry picked for removal by one will be skipped by the rest
    and we'll go for the next iteration through the entire
    subtree, even if everything is being skipped.  Morevoer, we
    immediately go back to scanning the subtree.  The only thing
    we really need is to dissolve all mounts in the subtree and
    as soon as we've nothing left to do, we can just unhash the
    dentry and bugger off.

    ufs_truncate_blocks(): fix the case when size is in the last direct block
    The logics when deciding whether we need to do anything with direct blocks
    is broken when new size is within the last direct block.  It's better to
    find the path to the last byte _not_ to be removed and use that instead
    of the path to the beginning of the first block to be freed...

    ufs: avoid grabbing ->truncate_mutex if possible
    tail unpacking is done in a wrong place; the deadlocks galore
    is best dealt with by doing that in ->write_iter() (and switching
    to iomap, while we are at it), but that's rather painful to
    backport.  The trouble comes from grabbing pages that cover
    the beginning of tail from inside of ufs_new_fragments(); ongoing
    pageout of any of those is going to deadlock on ->truncate_mutex
    with process that got around to extending the tail holding that
    and waiting for page to get unlocked, while ->writepage() on
    that page is waiting on ->truncate_mutex.
    The thing is, we don't need ->truncate_mutex when the fragment
    we are trying to map is within the tail - the damn thing is
    allocated (tail can't contain holes).
    Let's do a plain lookup and if the fragment is present, we can
    just pretend that we'd won the race in almost all cases.  The
    only exception is a fragment between the end of tail and the
    end of block containing tail.
    Protect ->i_lastfrag with ->meta_lock - read_seqlock_excl() is

    callers rely upon that, but find_lock_page() racing with attempt of
    page eviction by memory pressure might have left us with

        * __remove_mapping() failed, leaving the page in our mapping
        * find_lock_page() returning an uptodate page with no
    buffer_heads attached.

    ufs: fix s_size/s_dsize users
    For UFS2 we need 64bit variants; we even store them in uspi, but
    use 32bit ones instead.  One wrinkle is in handling of reserved
    space - recalculating it every time had been stupid all along, but
    now it would become really ugly.  Just calculate it once...

    ufs: fix logics in "ufs: make fsck -f happy"
    Storing stats _only_ at new locations is wrong for UFS1; old
    locations should always be kept updated.  The check for "has
    been converted to use of new locations" is also wrong - it
    should be "->fs_maxbsize is equal to ->fs_bsize".

    xfs: fix spurious spin_is_locked() assert failures on non-smp kernels
    The 0-day kernel test robot reports assertion failures on
    !CONFIG_SMP kernels due to failed spin_is_locked() checks. As it
    turns out, spin_is_locked() is hardcoded to return zero on
    !CONFIG_SMP kernels and so this function cannot be relied on to
    verify spinlock state in this configuration.
    To avoid this problem, replace the associated asserts with lockdep
    variants that do the right thing regardless of kernel configuration.
    Drop the one assert that checks for an unlocked lock as there is no
    suitable lockdep variant for that case. This moves the spinlock
    checks from XFS debug code to lockdep, but generally provides the
    same level of protection.
