mutexes and modules

2003-01-07 Thread Andrew Gallatin 

Are kernel modules pessimized in any way with respect to using
mutexes as compared to statically compiled kernel code?

I seem to remember some discussion a year or more ago indicating that
they would be, but I'm not seeing it in the code.

Thanks,

Drew

In the non debug case the quick cases are not inlined in modules but
are always function calls.  Other than that there isn't much difference.
