commit f9fd0135610084abef6867d984e9951c3099950d

    xfs: don't perform discard if the given range length is less than block size
    
    For discard operation, we should return EINVAL if the given range length
    is less than a block size, otherwise it will go through the file system
    to discard data blocks as the end range might be evaluated to -1, e.g,
    # fstrim -v -o 0 -l 100 /xfs7
    /xfs7: 9811378176 bytes were trimmed
    
    This issue can be triggered via xfstests/generic/288.
    
    Also, it seems to get the request queue pointer via bdev_get_queue()
    instead of the hard code pointer dereference is not a bad thing.

    xfs: underflow bug in xfs_attrlist_by_handle()
    
    If we allocate less than sizeof(struct attrlist) then we end up
    corrupting memory or doing a ZERO_PTR_SIZE dereference.
    
    This can only be triggered with CAP_SYS_ADMIN.

    xfs: simplify xfs_setsize_buftarg callchain; remove unused arg
    
    The "verbose" argument to xfs_setsize_buftarg_flags() has been
    unused since:
    
    ffe37436 xfs: stop using the page cache to back the buffer cache
    
    Remove it, and fold the function into xfs_setsize_buftarg()
    now that there's no need for different types of callers.
    
    Fix inconsistent comment spacing while we're at it.
