mainlining shenanigans
Currently bits in hba->outstanding_tasks are cleared only after their corresponding task management commands are successfully done by __ufshcd_issue_tm_cmd(). If timeout happens in a task management command, its corresponding bit in hba->outstanding_tasks will not be cleared until next task management command with the same tag used successfully finishes. This is wrong and can lead to some issues, like power issue. For example, ufshcd_release() and ufshcd_gate_work() will do nothing if hba->outstanding_tasks is not zero even if both UFS host and devices are actually idle. Solution is referred from error handling of device commands: bits in hba->outstanding_tasks shall be cleared regardless of their execution results.

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 Restructured Text 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.
