Is it valid to call bio_endio() > from the map() function for individual target types? Yes, this can definitely happen. For a simple example, see dm-zero.c::zero_map(). Another common example would be anyplace that needs to call bio_io_error() in the I/O-submit path, which is just a macro around bio_endio(). Hope that helps. :) -- Kevin Corry kevcorry@xxxxxxxxxx http://www.ibm.com/linux/ http://evms.sourceforge.net/ -- dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
