A lot of this overhead comes from silly inefficiencies. This pull request contains fixes for the low-hanging fruit. The fixes are all fairly small and straightforward. The result is a 25% improvement in read latency in micro-benchmarks (from ~235 nanoseconds to ~175) and a 15% improvement in execution time for real-world drgn scripts: - Make /proc/kcore entry permanent - Avoid walking the list on every read - Use percpu_rw_semaphore for kclist_lock - Make Omar Sandoval the official maintainer for /proc/kcore" * tag 'vfs-6.14-rc1.kcore' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: MAINTAINERS: add me as /proc/kcore maintainer proc/kcore: use percpu_rw_semaphore for kclist_lock proc/kcore: don't walk list on every read proc/kcore: mark proc entry as permanent |

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.
