We set SA_RESTART early on, which will prevent EINTRs (indeed, to the point of needing to clear it in the reaper, since it interferes with pause(2)), which is the only error zed_file_write_n() actually handled (plus, the pid write is no bigger than 12 bytes anyway) Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #11834
