Add Clang flags and kconfig options for measuring the kernel's modified
condition/decision coverage (MC/DC).
As of Clang 19, users can determine the max number of conditions in a
decision to measure via option LLVM_COV_KERNEL_MCDC_MAX_CONDITIONS,
which controls -fmcdc-max-conditions flag of Clang
Disable instrumentation in the same areas that were disabled for

Implement debugfs entries for serializing profiles and resetting
counters/bitmaps. Also adds Source-based Code Coverage flags and kconfig
options.
This work reuses a portion of code from a previous effort by Sami
Tolvanen et al. [1], specifically its debugfs interface and the
underlying profile pr
This series adds support for building x86-64 kernels with Clang's Source-
based Code Coverage[1] in order to facilitate Modified Condition/Decision
Coverage (MC/DC)[2] that provably correlates to source code for all levels
of compiler optimization.
The newly added kernel/llvm-cov/ directory comple
The execute_syscall_skas() have been removed since
commit e32dacb9f481 ("[PATCH] uml: system call path cleanup"),
and now it is useless, so remove it.
