blk-mq: setup queue ->tag_set before initializing hctx
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: setup queue ->tag_set before initializing hctx
Commit 7b815817aa58 ("blk-mq: add helper for checking if one CPU is mapped to specified hctx")
needs to check queue mapping via tag set in hctx's cpuhp handler.
However, q->tag_set may not be setup yet when the cpuhp handler is
enabled, then kernel oops is triggered.
Fix the issue by setup queue tag_set before initializing hctx.Daten sind bereitgestellt durch National Vulnerability Database (NVD)
