Kirk McKusick 6dff61a1d1 Rate limit kernel UFS/FFS cylinder group check-hash error messages.
When a large file is deleted or a large number of files are deleted,
even a single cylinder group with a bad check hash can generate
thousands of check-hash warnings. As with other filesystem messages
such as out-of-space, print a maximum of one check-hash error per
second. Note the limit is per filesystem. If two filesystems have
cylinder group(s) with a bad check hash, each will print a maximum
of one check-hash error message per second.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.

For information on the CPU architectures and platforms supported by FreeBSD, see the FreeBSD website's Platforms page.
