is_debugfs_mounted

is_debugfs_mounted();

Checks whether debugfs is mounted at /sys/kernel/debug, same check as blktests' _have_debugfs(). Returns true/false.

enable_debugfs

enable_debugfs();

Mounts debugfs at /sys/kernel/debug (e.g. on SLE 16.1+, where it is disabled by default per PED-8812).

get_kernel_config

get_kernel_config();

Locates the running kernel's config file (/boot/config-$(uname -r), falling back to /usr/lib/modules/$(uname -r)/config and then /proc/config.gz) and records its full contents via record_info(), prefixed with a comment naming the source file (as done in LTP::utils::log_versions).
