xfs: remove XFS_BMAP_TRACE_EXLIST
Instead of looping over all extents in some debug-only helper just insert trace points into the loops that already exist in the calling functions. Also split the xfs_extlist trace point into one each for reading and writing extents from disk. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
