In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warnings:
drivers/block/drbd/drbd_receiver.c: In function ‘drbd_asb_recover_0p’:
drivers/block/drbd/drbd_receiver.c:3093:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (self == 1 && peer == 0) {
^
drivers/block/drbd/drbd_receiver.c:3098:2: note: here
case ASB_DISCARD_OLDER_PRI:
^~~~
drivers/block/drbd/drbd_receiver.c:3120:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (after_sb_0p == ASB_DISCARD_ZERO_CHG)
^
drivers/block/drbd/drbd_receiver.c:3123:2: note: here
case ASB_DISCARD_LEAST_CHG:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that in some cases, the code comment is modified in
accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
