The IO context conversion for rw_bytes missed a case in the BTT write path (btt_map_write) which should've been marked as atomic. In reality this should not cause a problem, because map writes are to small for nsio_rw_bytes to attempt error clearing, but it should be fixed for posterity. Add a might_sleep() in the non-atomic section of nsio_rw_bytes so that things like the nfit unit tests, which don't actually sleep, can catch bugs like this.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
