Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
0f439c746c
When called with CHECK_CAPS_AUTHONLY flag, ceph_check_caps() only processes auth caps. In that case, it's unsafe to remove inode from mdsc->cap_delay_list, because there can be delayed non-auth caps. Besides, ceph_check_caps() may lock/unlock i_ceph_lock several times, when multiple threads call ceph_check_caps() at the same time. It's possible that one thread calls __cap_delay_requeue(), another thread calls __cap_delay_cancel(). __cap_delay_cancel() should be called at very beginning of ceph_check_caps(), so that it does not race with __cap_delay_requeue().

README
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.
