Hi,

commit 26574401fef6766f6c3ca25b5c13febe662d2a32 "net: Fix ipoib rtnl_lock
sysfs deadlock" modified some flows doing rtnl_lock calls to use rtnl_trylock
/ restart_syscall, etc. It turned out that restart_syscall was included in
ipoib through linux/inet_lro.h which is an include I'd like to remove...
Is including linux/sched.h being the right thing to do? I wasn't sure as
this call is very rare, in network drivers its called only by ipoib and
bonding and it looks like bonding includes it indirectly.

Or.

For the definition of restart_syscall yes.

I wish I was clever enough to find a way not to need rtnl_trylock
restart_syscall but unfortunately I don't :(
