The KCSAN tool emits a great many warnings for current kernels, for example, a one-hour run of the full set of rcutorture scenarios results in no fewer than 3252 such warnings, many of which are duplicates or are otherwise closely related. This commit therefore introduces a kcsan-collapse.sh script that maps these warnings down to a set of function pairs (22 of them given the 3252 individual warnings), placing the resulting list in decreasing order of frequency of occurrence into a kcsan.sum file. If any KCSAN warnings were produced, the pathname of this file is emitted at the end of the summary of the rcutorture runs. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
