Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

The only context that frees user_exp_rcv data structures is the last context closed (from a sub-context set). This leaks the allocations from the other sub-contexts. Separate the common frees from the specific frees and call them at the appropriate time. Using KEDR to check for memory leaks we get: Before test: [leak_check] Possible leaks: 25 After test: [leak_check] Possible leaks: 31 (6 leaked data structures) After patch applied (before and after test have the same value) [leak_check] Possible leaks: 25 Each leak is 192 + 13440 + 6720 = 20352 bytes per sub-context.

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.
