I haven't looked on it yet, but I think should be really easy from disk driver point ov view. After last firmware update, my SSD should now support TRIM, so I will look on it closer, as time permit. The main question is to implement BIO_DELETE in filesystems code. I have seen in lists that UFS patches were made long time ago, but they are still not committed. Now practically the only BIO_DELETE consumer is newfs with -E option, which I have successfully used with mmcsd driver. -- Alexander MotinReceived on Sat Jun 27 2009 - 09:02:05 UTC
