Hi- [ please Cc: me, I'm not subscribed to linux-mm ] We've been discussing how NFSD can more efficiently refill its receive buffers (currently alloc_page() in a loop; see net/sunrpc/svc_xprt.c::svc_alloc_arg()). Neil Brown pointed me to this old thread: https://lore.kernel.org/lkml/20170109163518.6001-1-mgorman@xxxxxxxxxxxxxxxxxxx/ We see that many of the prerequisites are in v5.11-rc, but alloc_page_bulk() is not. I tried forward-porting 4/4 in that series, but enough internal APIs have changed since 2017 that the patch does not come close to applying and compiling. I'm wondering: a) is there a newer version of that work? b) if not, does there exist a preferred API in 5.11 for bulk page allocation? Many thanks for any guidance! -- Chuck Lever
