Subject: [PATCH] [linux] fix segfault when eventpoll fdinfo is unavailable

process_id() pre-fills -1 sentinels for the oty == 0 case, but tfd_count is size_t, so -1 becomes SIZE_MAX and the `fi.tfd_count > 0` guard passes where the `!= -1` siblings skip. snp_eventpoll() then qsorts SIZE_MAX entries of a 32-entry array. Declare it int, matching tfds[], the snp_eventpoll() parameters and the eventfd_id/pid sentinels.
