Darrick J. Wong	c866515f02	undo-io: add new calls to and speed up the undo io manager ... Implement pass-through calls for discard, zero-out, and readahead in the IO manager so that we can take advantage of any underlying support. Furthermore, improve tdb write-out speed by disabling locking and only fsyncing at the end -- we don't care about locking because having multiple writers to the undo file will produce an undo database full of garbage blocks; and we only need to fsync at the end because if we fail before the end, our undo file will lack the necessary superblock data that e2undo requires to do replay safely. Without this, we call fsync four times per tdb update(!) This reduces the overhead of using undo_io while converting a 2TB FS to metadata_csum from 3+ hours to 55 minutes. Signed-off-by: Darrick J.
