- spin_lock(&shca_list_lock); + spin_lock_irqsave(&shca_list_lock, flags);That's wrong and I think will give a warning on all machines where u64 != unsigned long. Might not particularly matter in this case.
Crud, sorry.
Also, generally it seems wrong to say "fix lockdep failure" when the patch really fixes a bug that lockdep happened to find.
True. I guess it should be "fix locking error found with lockdep", to make it clear no one has actually hit the bug. cheers -- Michael Ellerman OzLabs, IBM Australia Development Lab wwweb: http://michael.ellerman.id.au phone: +61 2 6212 1183 (tie line 70 21183) We do not inherit the earth from our ancestors, we borrow it from our children. - S.M.A.R.T Person
