net-sysfs: Use rtnl_trylock in sysfs methods.
The earlier patch to fix the deadlock between a network device going away and writing to sysfs attributes was incomplete. - It did not set signal_pending so we would leak ERSTARTSYS to user space. - It used ERESTARTSYS which only restarts if sigaction configures it to. - It did not cover store and show for ifalias. So fix all of these up and use the new helper restart_syscall so we get the details correct on what it takes. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S.
