    f2fs: fix to detect truncation prior rather than EIO during read · 1563ac75
    Chao Yu authored
    In procedure of synchonized read, after sending out the read request, reader
    will try to lock the page for waiting device to finish the read jobs and
    unlock the page, but meanwhile, truncater will race with reader, so after
    reader get lock of the page, it should check page's mapping to detect
    whether someone has truncated the page in advance, then reader has the
    chance to do the retry if truncation was done, otherwise read can be failed
    due to previous condition check.
