CVS commit: src/sys/dev/ic

Modified Files:
        src/sys/dev/ic: mfi.c

Log Message:
mfi.c still uses the spl() synchronisation scheme and so needs the kernel lock.
The sysmon subsystem is marked MPSAFE and so runs without the kernel lock.
So get the kernel lock in mfi_sensor_refresh()  before calling
mfi_ioctl_vol().
This fixes command list corruption seen on heavy I/O load on the mfi
driver(4).
