| |
Hi Jens, here are a few more patches from my set that makes various changes to bio submission and handling.
These change the ->bi_end_io prototype so that 1/ no 'size' is passed 2/ there is no return value.
The 'size' is not really of interest to any bi_end_io handler in existance. It is really only an internal detail to the "request" handling in ll_rw_blk and lower levels. The return value is completely unused.
After these patches, ->bi_end_io is only ever called once per bio.
Note that the last patch makes lots and lots of simple changes. I think I have found all the right places, but any recently added device drivers might still be using the old bi_end_io prototype. I'll grep again after these patches are in your tree.
That patches are against linux-block as of an hour ago.
Thanks, NeilBrown
