commit 24366c2afbb0539fb14eff330d4e3a5db5c0a3ef upstream. bkops level should be rechecked upon receiving an exception. Currently the level is being cached and never updated. Update bkops each time the level is checked. Also do not use the cached bkops level value if it is disabled and then enabled. Fixes: afdfff59a0e0 (scsi: ufs: handle non spec compliant bkops behaviour by device) Link: https://lore.kernel.org/r/1574751214-8321-2-git-send-email-cang@qti.qualcomm.com Reviewed-by: Bean Huo <beanhuo@micron.com> Reviewed-by: Alim Akhtar <alim.akhtar@samsung.com> Tested-by: Alim Akhtar <alim.akhtar@samsung.com> Signed-off-by: Asutosh Das <asutoshd@codeaurora.org> Signed-off-by: Can Guo <cang@codeaurora.org> Signed-off-by: Martin K.

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.
