Adjust the rss_stat tracepoint to print the name of the resident page type that got updated (e.g. MM_ANONPAGES/MM_FILEPAGES), rather than the numeric index corresponding to it (the __entry->member value): Before this patch: ------------------ rss_stat: mm_id=1216113068 curr=0 member=1 size=28672B rss_stat: mm_id=1216113068 curr=0 member=1 size=0B rss_stat: mm_id=534402304 curr=1 member=0 size=188416B rss_stat: mm_id=534402304 curr=1 member=1 size=40960B After this patch: ----------------- rss_stat: mm_id=1726253524 curr=1 type=MM_ANONPAGES size=40960B rss_stat: mm_id=1726253524 curr=1 type=MM_FILEPAGES size=663552B rss_stat: mm_id=1726253524 curr=1 type=MM_ANONPAGES size=65536B rss_stat: mm_id=1726253524 curr=1 type=MM_FILEPAGES size=647168B Use TRACE_DEFINE_ENUM()/__print_symbolic() logic to map the enum values to the strings they represent, so that userspace tools can also parse the raw data correctly.

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.
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.
