fault-injection: cleanup simple attribute of stacktrace_depth
Minor cosmetic changes for simple attribute of stacktrace_depth: - use min_t() - reduce #ifdef by moving a function - do not use partly capitalized function name Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
