Hello all,
Nvidia document explains that,  in order for a filesystem to support
GDS (gpu direct storage) the FS needs to make a callback to
"nvidis-fs.ko"  to translate a virtual address to GPU physical address
for DMA.   However I'm unable to find the callback in XFS code.  I'm
curious how can XFS support GDS without calling nvidia callbacks?


regards,
Shawn

nidia needs to f**king stop violating our copyrights and just go away.
