ext4: generalize EXT4_GET_BLOCKS_IO_SUBMIT flag usage
Currently, the EXT4_GET_BLOCKS_IO_SUBMIT flag is only used during data
writeback to indicate that in ordered mode, the journal commit thread
should skip re-submitting data and simply wait for I/O completion.
To prepare for later patches that need to detect I/O submission context
in ext4_map_blocks(), generalizes the meaning of
EXT4_GET_BLOCKS_IO_SUBMIT. This flag will be set during:
1) data I/O writeback,
2) I/O completion extents conversion,
3) journal performing commit in fast_commit.
This change doesn't affect current usage of this flag and provides a
clear way to identify I/O submission context.
