I get struct size mismatch between ncrcontrol and a freshly compiled kernel
(obviously this leads to ncrcontrol being unusable). I don't understand
why... After several kernel/ncrcontrol recompiles, the problem persists.
ncrcontrol think ncr_version (generated in /sys/pci/ncr.c with various
sizes) is 26402 and the kernel has 27186 !
Within /sys/pci/ncr.c:
#define NCR_VERSION (2)
static const u_long ncr_version = NCR_VERSION * 11
+ (u_long) sizeof (struct ncb) * 7
+ (u_long) sizeof (struct ccb) * 5
+ (u_long) sizeof (struct lcb) * 3
+ (u_long) sizeof (struct tcb) * 2;
A test with ncrcontrol leads to:
sizeof ncb=3356 sizeof ccb=500 sizeof lcb=36 sizeof tcb=140
2*11 + 7*3356 + 5*500 + 3*36 + 2*140 = 26402.
Why the kernel is thinking ncr_version is 27186 ?!? I've checked with DDB.
Which structure(s) gets a different size ?
Here are the relevant part of /etc/make.conf:
COPTFLAGS= -O -pipe
CFLAGS= -O -pipe
