Hell Andrew and Al, Since no more feedback from RFC V3, I suppose the series could be ready for merge. And Song has already acked the md patch, then all the rest patches are for fs and mm. So, if no further comments for the patchset, could you consider to queue them from either of your tree to avoid potential build issue? Thank you! RFC V3: https://lore.kernel.org/lkml/20200507214400.15785-1-guoqing.jiang@xxxxxxxxxxxxxxx/ RFC V3: https://lore.kernel.org/lkml/20200430214450.10662-1-guoqing.jiang@xxxxxxxxxxxxxxx/ RFC: https://lore.kernel.org/lkml/20200426214925.10970-1-guoqing.jiang@xxxxxxxxxxxxxxx/ Thanks, Guoqing No change since RFC V3. RFC V2 -> RFC V3: 1. rename clear_page_private to detach_page_private. 2. Update the comments for attach/detach_page_private from Mattew. 3. add one patch to call new function in mm/migrate.c as suggested by Mattew, but use the conservative way to keep the orginal semantics [2]. RFC -> RFC V2: 1. rename the new functions and add comments for them. 2. change the return type of attach_page_private. 3. call attach_page_private(newpage, clear_page_private(page)) to cleanup code further. 4. avoid potential use-after-free in orangefs.
