|| ||[PATCH 000 of 4] Change prototype for bi_end_io|
|| ||Thu, 27 Sep 2007 17:20:01 +1000|
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.
Net result of the 4 patches:
