Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.

usb_get_status(9F) Kernel Functions for Drivers usb_get_status(9F)
NAME
usb_get_status - Get status of a USB device/endpoint/interface
SYNOPSIS
#include <sys/usb/usba.h>
int usb_get_status(dev_info_t *dip, usb_pipe_handle_t pipe_handle,
uint_t request_type, uint_t which, uint16_t *status,
usb_flags_t flags);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
dip Pointer to device's dev_info structure.
pipe_handle Default control pipe handle on which request is made.
request_type bmRequestType. Either:
USB_DEV_REQ_RCPT_DEV -- Get device status.
USB_DEV_REQ_RCPT_IF -- Get interface status.
USB_DEV_REQ_RCPT_EP -- Get endpoint status.
which Device, interface or endpoint from which to get status. Either number of interface or endpoint, or 0 if device status
requested.
status Address into which the status is written.
flags None are recognized.
DESCRIPTION
The usb_get_status() function returns the status of a device, interface or endpoint. All status requests use the default control pipe.
Length of data returned is USB_GET_STATUS_LEN bytes. Always block and wait for resources if not available, regardless of the flags argu-
ment.
When the request_type recipient is USB_DEV_REQ_RCPT_DEV, device status is requested. Status returned includes bits for
USB_DEV_SLF_PWRD_STATUS (device is currently self-powered) and USB_DEV_RWAKEUP_STATUS (device has remote wakeup enabled). A set bit
indicates the corresponding status.
When the request_type is USB_DEV_REQ_RCPT_EP, endpoint status is requested. Status returned includes bits for USB_EP_HALT_STATUS (endpoint
is halted). A set bit indicates the corresponding status.
When the request_type is USB_DEV_REQ_RCPT_IF, interface status is requested and USB_IF_STATUS (zero) is returned.
RETURN VALUES
USB_SUCCESS Status returned successfully in the status argument.
USB_INVALID_ARGS Status pointer and/or dip argument is NULL.
USB_INVALID_PIPE Pipe handle is NULL.
USB_FAILURE Status not returned successfully.
CONTEXT
May be called from user or kernel context.
EXAMPLES
uint16_t status;
if (usb_get_status(
dip, pipe_handle, USB_DEV_REQ_RCPT_DEV, 0 &status, 0) ==
USB_SUCCESS) {
if (status & USB_DEV_SLF_PWRD_STATUS) {
cmn_err (CE_WARN,
"%s%d: USB device is running on its own power.",
ddi_driver_name(dip), ddi_get_instance(dip));
}
}
