![]() Delaying key quotas update when key's refcount reaches 0 in key_put() has been causing some issues in fscrypt testing, specifically in fstest generic/581. This commit fixes this test flakiness by dealing with the quotas immediately, and leaving all the other clean-ups to the key garbage collector. This is done by moving the updates to the qnkeys and qnbytes fields in struct key_user from key_gc_unused_keys() into key_put(). Unfortunately, this also means that we need to switch to the irq-version of the spinlock that protects these fields and use spin_lock_{irqsave,irqrestore} in all the code that touches these fields.

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.
