Revision f2ebf8ffe7af10bff02d34addbebd9199de65ed2 authored by Riccardo Mancini on 15 July 2021, 16:07:21 UTC, committed by Arnaldo Carvalho de Melo on 15 July 2021, 20:34:39 UTC
ASan reports several memory leaks running: # perf test "88: Check open filename arg using perf trace + vfs_getname" The second of these leaks is caused by the arg_fmt field of syscall not being deallocated. This patch adds a new function syscall__exit which is called on all syscalls.table entries in trace__exit, which will free the arg_fmt field.
