Hi Jens,
After merging the block tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
block/blk-flush.c: In function 'flush_data_end_io':
block/blk-flush.c:369:20: error: 'REQ_STARTED' undeclared (first use in this function)
rq->cmd_flags &= ~REQ_STARTED;
^
Caused by commit
e806402130c9 ("block: split out request-only flags into a new namespace")
interacting with commit
94d7dea448fa ("block: flush: fix IO hang in case of flood fua req")
from Linus' tree (v4.9-rc3).
I have applied the following merge fix patch for today (I don't know if
this is correct, but it does build):
