Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

xfs: define fatal assert build time tunable While configurable at runtime, the DEBUG mode assert failure behavior is usually either desired or not for a particular situation. For example, developers using kernel modules may prefer for fatal asserts to remain disabled across module reloads while QE engineers doing broad regression testing may prefer to have fatal asserts enabled on boot to facilitate data collection for bug reports. To provide a compromise/convenience for developers, create a Kconfig option that sets the default value of the DEBUG mode 'bug_on_assert' sysfs tunable. The default behavior remains to trigger kernel BUGs on assert failures to preserve existing behavior across kernel configuration updates with DEBUG mode enabled.

xfs: introduce CONFIG_XFS_WARN Running a CONFIG_XFS_DEBUG kernel in production environments is not the best idea as it introduces significant overhead, can change the behaviour of algorithms (such as allocation) to improve test coverage, and (most importantly) panic the machine on non-fatal errors. There are many cases where all we want to do is run a kernel with more bounds checking enabled, such as is provided by the ASSERT() statements throughout the code, but without all the potential overhead and drawbacks. This patch converts all the ASSERT statements to evaluate as WARN_ON(1) statements and hence if they fail dump a warning and a stack trace to the log. This has minimal overhead and does not change any algorithms, and will allow us to find strange "out of bounds" problems more easily on production machines. There are a few places where assert statements contain debug only code. These are converted to be debug-or-warn only code so that we still get all the assert checks in the code.
