*	sys: Automated cleanup of cdefs and other formatting	Warner Losh	2023-11-27	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Apply the following automated changes to try to eliminate no-longer-needed sys/cdefs.h includes as well as now-empty blank lines in a row. Remove /^#if.\n#endif.\n#include\s+<sys/cdefs.h>.\n/ Remove /\n+#include\s+<sys/cdefs.h>.\n+#if.\n#endif.\n+/ Remove /\n+#if.\n#endif.\n+/ Remove /^#if.\n#endif.\n/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/types.h>/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/param.h>/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/capsicum.h>/ Sponsored by: Netflix

*	spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD	Warner Losh	2023-05-12	1	-1/+1
\| \| \| \| \| \| \| \| \|	The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

*	pidctrl_daemon() implements a variation on the classical, discrete PID	Alan Cox	2018-06-07	1	-16/+16
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	controller that tries to handle early invocations of the controller, in other words, invocations before the expected end of the interval. However, there were some calculation errors in this early invocation case. Notably, if an early invocation occurred while the error was negative, the derivative term was off by a large amount. One visible effect of this error was that processes were being killed by the virtual memory system's OOM killer when in fact there was plentiful free memory. Correct a couple minor errors in the sysctl descriptions, and apply some style fixes. Reviewed by: jeff, markj Notes: svn path=/head/; revision=334752

This provides much smoother and more responsive page daemon output, anticipating demand and avoiding pageout stalls by increasing the number of pages to match the workload. This is a reimplementation of work done by myself and mlaier at Isilon.
