commit e001873853d87674dd5b3cfa2851885023616695

    xfs: ensure we capture IO errors correctly
    
    Failed buffer readahead can leave the buffer in the cache marked
    with an error. Most callers that then issue a subsequent read on the
    buffer do not zero the b_error field out, and so we may incorectly
    detect an error during IO completion due to the stale error value
    left on the buffer.
    
    Avoid this problem by zeroing the error before IO submission. This
    ensures that the only IO errors that are detected those captured
    from are those captured from bio submission or completion.

    xfs: fix xfs_iomap_eof_prealloc_initial_size type
    
    Fix the return type of xfs_iomap_eof_prealloc_initial_size() to
    xfs_fsblock_t to reflect the fact that the return value may be an
    unsigned 64 bits if XFS_BIG_BLKNOS is defined.

    xfs: fix potential infinite loop in xfs_iomap_prealloc_size()
    
    If freesp == 0, we could end up in an infinite loop while squashing
    the preallocation. Break the loop when we've killed the prealloc
    entirely.
