Revision 2e85d32b1c865bec703ce0c962221a5e955c52c2 authored by SeongJae Park on 14 December 2020, 09:04:18 UTC, committed by Juergen Gross on 14 December 2020, 09:04:18 UTC
Some code does not directly make 'xenbus_watch' object and call 'register_xenbus_watch()' but use 'xenbus_watch_path()' instead. This commit adds support of 'will_handle' callback in the 'xenbus_watch_path()' and it's wrapper, 'xenbus_watch_pathfmt()'.
