However, that doesn't handle in-kernel use of the fpu. kernel_fpu_begin()/kernel_fpu_end() could easily be modified to take advantage of a generic preempt hook. I'll add a patch for that, and we gain preemptible raid-5 parity calculation. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
