We decide to push this feature as it is useful for NAS or virt environment. The patches are against the mmotm-2010-07-01. We can split the patchset into following parts: Patch 1 - 12: provides a generic reserve framework. This framework could also be used to get rid of some of the __GFP_NOFAIL users. Patch 13 - 15: Provide some generic network infrastructure needed later on. Patch 16 - 21: reserve a little pool to act as a receive buffer, this allows us to inspect packets before tossing them. Patch 22 - 23: Generic vm infrastructure to handle swapping to a filesystem instead of a block device. Patch 24 - 27: convert NFS to make use of the new network and vm infrastructure to provide swap over NFS. Patch 28 - 30: minor bug fixing with latest -mmotm. [some history] v19: http://lwn.net/Articles/301915/ v20: http://lwn.net/Articles/355350/ Changes since v20: - rebased to mmotm-2010-07-01 - dropped the null pointer deref patch for the root cause is wrong SWP_FILE enum - some minor build fixes - fix a null pointer deref with mmotm-2010-07-01 - fix a bug when swap with multi files on the same nfs server Regards Xiaotian -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
