But there is really no need tounmap anyway, since mmap(MAP_FIXED) will happily clobber the existingmapping with zeroes. This is thread-safe since the mmap() is done underthe same kernel lock as page faults are done.Reviewed By: vitalybukaDifferential Revision: https://reviews.llvm.org/D85947 List of files: /llvm-project-15.0.7/compiler-rt/test/dfsan/threaded_flush.c Fri, 14 Aug 2020 18:43:33 +0000 Matt Morehouse <mascasa@google.com>
