This break EPIPE handling inside splice when SIGPIPE is ignored:
Before:
$ { sleep 1; strace -e splice pv -q /dev/zero; } | :
splice(3, NULL, 1, NULL, 131072, SPLICE_F_MORE) = -1 EPIPE (Broken pipe)
--- SIGPIPE {si_signo=SIGPIPE, si_code=SI_USER, si_pid=23750, si_uid=17005} ---
--- SIGPIPE {si_signo=SIGPIPE, si_code=SI_USER, si_pid=23750, si_uid=17005} ---
+++ exited with 0 +++
After:
$ { sleep 1; strace -e splice pv -q /dev/zero; } | :
splice(3, NULL, 1, NULL, 131072, SPLICE_F_MORE) = 65536
splice(3, NULL, 1, NULL, 131072, SPLICE_F_MORE
[hangs]
