- Summary
- md/raid1,raid10: don't ignore IO flags
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
md/raid1,raid10: don't ignore IO flags
If blk-wbt is enabled by default, it's found that raid write performance is quite bad because all IO are throttled by wbt of underlying disks, due to flag REQ_IDLE is ignored. And turns out this behaviour exist since blk-wbt is introduced.
Other than REQIDLE, other flags should not be ignored as well, for example REQMETA can be set for filesystems, clearing it can cause priority reverse problems; And REQ_NOWAIT should not be cleared as well, because io will wait instead of failing directly in underlying disks.
Fix those problems by keep IO flags from master bio.
