[Qemu-devel] [PATCH 1/4] rbd: remove unused constants and fields |
Date: |
Wed, 10 Jun 2015 20:28:43 -0700 |
RBDAIOCB.status was only used for cancel, which was removed in
7691e24dbebb46658e89b3f950fda6ec78bbb823.
RBDAIOCB.sector_num was never used.
RADOSCB.done and rcbid were never used.
RBD_FD* are obsolete since the pipe was removed in
e04fb07fd1676e9facd7f3f878c1bbe03bccd26b.
