use libsysfs for udevstart directory walking

Hi

Following up on Kay's idea about using libsysfs for directory walking.

Attached patch(against udev-032) is a first cut attempt at replacing udev_scan_class directory walking code with libsysfs calls. If we agree on this approach, I'll do the same for udev_scan_block.

Currently, libsysfs does not provide an API for getting all the classes. So, I've introduced two new functions in libsysfs:

struct dlist *sysfs_open_classes(void)
void sysfs_close_classes(struct dlist *clslist)

Comments/flames?

Sorry to reply to my own post.

I was wrong about this.

Remco <[email protected]>, pointed out to me that libsysfs provides these functionalities with the following two APIs:

struct dlist *sysfs_open_subsystem_list(char *name) void sysfs_close_list(struct dlist *list)

Just ignore this patch. I'll resend the patch which uses the above APIs.
