Move flush queue allocation into blk_mq_init_hctx() and its release into blk_mq_exit_hctx(), and prepare for replacing tags->lock with SRCU to draining inflight request walking. blk_mq_exit_hctx() is the last chance for us to get valid `tag_set` reference, and we need to add one SRCU to `tag_set` for freeing flush request via call_srcu(). It is safe to move flush queue & request release into blk_mq_exit_hctx(), because blk_mq_clear_flush_rq_mapping() clears the flush request reference int driver tags inflight request table, meantime inflight request walking is drained.

Linux kernel
There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.
In order to build the documentation, use make htmldocs or
make pdfdocs. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
