MFC the enhancements to the Linux emulation layer so the MegaRAID SAS

management tools can work. This is not totally connected to the build yet. The mfi(4) change have not been MFC'ed yet. This will be done shortly. I'm trying to do this in chunks so I don't totally break the build on a missed commit. This has passed make universe a while ago: Enhance the Linux emulation layer to make MegaRAID SAS managements tool happy. Add back in a scheme to emulate old type major/minor numbers via hooks into stat, linprocfs to return major/minors that Linux app's expect. Currently only /dev/null is always registered. Drivers can register via the Linux type shim similar to the ioctl shim but by using linux_device_register_handler/linux_device_unregister_handler functions. The structure is: struct linux_device_handler { char *bsd_driver_name; char *linux_driver_name; char *bsd_device_name; char *linux_device_name; int linux_major; int linux_minor; int linux_char_device; }; Linprocfs uses this to display the major number of the driver. The soon to be available linsysfs will use it to fill in the driver name. Linux_stat uses it to translate the major/minor into Linux type values. Note major numbers are dynamically assigned via passing in a -1 for the major number so we don't need to keep track of them. This is somewhat needed due to us switching to our devfs.

Remove linux_emul_find() and the CHECKALT*() macros as they are no longer

Make linux_emul_convpath() a simple wrapper for kern_alternate_path().

VOP_GETATTR() wants the vnode passed to it to be locked. Instead

2004-01-14T22:38:03Z

of adding the code to lock and unlock the vnodes and taking care to avoid deadlock, simplify linux_emul_convpath() by comparing the vnode pointers directly instead of comparing their va_fsid and va_fileid attributes. This allows the removal of the calls to VOP_GETATTR().

Use __FBSDID().
