Add support for reporting per-uid information through procfs, roughly following the approach used for per-tid and per-tgid directories in fs/proc/base.c. This also entails some new tracking of which uids have been used, to avoid losing information when the last task with a given uid exits. Signed-off-by: Connor O'Brien <connoro@google.com> Bug: 72339335 Test: ls /proc/uid/; compare with UIDs in /proc/uid_time_in_state Change-Id: I0908f0c04438b11ceb673d860e58441bf503d478
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.
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.
