I'll release 1.0.0 the week after next (before Xmas). So if you guys have things to be merged, please send them. = From: FUJITA Tomonori <fujita.tomonori at lab.ntt.co.jp> Subject: [PATCH] remove doc/TODO The majority of the contents are outdated.

Then we need more tweaks in the user-space -code. - - -- user-space passthrough - -sg v4 is necessary for the user-space target drivers' passthrough. - - -- backing-storage disk images - -bd_mmap/aio support only raw images. They should support fancy disk -images (like QCOW, vmdk, etc) to enjoy snapshot without using LVM. -Adding QCOW to bd_mmap is quite simple, but a bit tricky to bd_aio -(see Xen's blktap code). Without code duplication, we need to add disk -images to both bd_mmap/aio. - - -- rearrange backing storage code - -Now the backing storage code includes: file I/O (bd_mmap/aio/xen) and -user-space passthrough (bd_sg). The design are hacky. The backing -storage code will be more complicated (supports the fancy disk images, -OSD, etc). We need to reconsider the design at some future time. - - -- kernel-space passthrough - -We need a new kernel module for the kernel-space target drivers' -passthrough. Seems it's ok by James as long as it's cleanly -implemented. - - -- persistent reservations - -Nice though I'm not sure this is that important. - - -- backing-storage virtualization - -Virtual tape support would be nice but it needs lot of work and I have -no plan to implement this. - -Virtual cdrom support isn't difficult but I'm not sure people really -need it. - - -- AIO event notification - -The user-space target drivers (only iSCSI now, possibly SRP later on) -need an event notification inferface to handle both synchronous and -asynchronous file descriptors. Now we use a workaround to use a I/O -helper thread (runs synchrnously to enable tgtd daemon run -asynchrnously). This workaround will be removed when upstream kernels -have a unified event notification interface (there are some candidates -under development). It should improve the tgt AIO performance too. -- 1.6.0.6 -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html |
