  "message": "Fix \u0027get_user_pages_fast()\u0027 with non-page-aligned start address\n\nAlexey Dobriyan reported trouble with LTP with the new fast-gup code,\nand Johannes Weiner debugged it to non-page-aligned addresses, where the\nnew get_user_pages_fast() code would do all the wrong things, including\njust traversing past the end of the requested area due to \u0027addr\u0027 never\nmatching \u0027end\u0027 exactly.\n\nThis is not a pretty fix, and we may actually want to move the alignment\ninto generic code, leaving just the core code per-arch, but Alexey\nverified that the vmsplice01 LTP test doesn\u0027t crash with this.\n\nReported-and-tested-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nDebugged-by: Johannes Weiner \u003channes@saeurebad.de\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
