      iomap: iomap that extends beyond EOF should be marked dirty · 7684e2c4
      Dave Chinner authored
      When doing a direct IO that spans the current EOF, and there are
      written blocks beyond EOF that extend beyond the current write, the
      only metadata update that needs to be done is a file size extension.
      
      However, we don't mark such iomaps as IOMAP_F_DIRTY to indicate that
      there is IO completion metadata updates required, and hence we may
      fail to correctly sync file size extensions made in IO completion
      when O_DSYNC writes are being used and the hardware supports FUA.
      
      Hence when setting IOMAP_F_DIRTY, we need to also take into account
      whether the iomap spans the current EOF. If it does, then we need to
      mark it dirty so that IO completion will call generic_write_sync()
      to flush the inode size update to stable storage correctly.
      
      Fixes: 3460cac1 ("iomap: Use FUA for pure data O_DSYNC DIO writes")
