    Subject[PATCH AUTOSEL 4.9 04/27] ext4: report real fs size after failed resize
    Date
    From: Lukas Czerner <lczerner@redhat.com>

    [ Upstream commit 6c7328400e0488f7d49e19e02290ba343b6811b2 ]

    Currently when the file system resize using ext4_resize_fs() fails it
    will report into log that "resized filesystem to <requested block
    count>". However this may not be true in the case of failure. Use the
    current block count as returned by ext4_blocks_count() to report the
    block count.

    Additionally, report a warning that "error occurred during file system
    resize"
