    ext4: fix bigalloc regression · d0abafac
    Eric Whitney 提交于
    Commit f5a44db5 introduced a regression on filesystems created with
    the bigalloc feature (cluster size > blocksize).  It causes xfstests
    generic/006 and /013 to fail with an unexpected JBD2 failure and
    transaction abort that leaves the test file system in a read only state.
    Other xfstests run on bigalloc file systems are likely to fail as well.
    
    The cause is the accidental use of a cluster mask where a cluster
    offset was needed in ext4_ext_map_blocks().
