#     mm/page_alloc: Correct return value of populated elements if bulk array is populated
#     
#     Dave Jones reported the following
#     
#             This made it into 5.13 final, and completely breaks NFSD for me
#             (Serving tcp v3 mounts).  Existing mounts on clients hang, as do
#             new mounts from new clients.  Rebooting the server back to rc7
#             everything recovers.
#     
#     The commit b3b64ebd3822 ("mm/page_alloc: do bulk array bounds check after
#     checking populated elements") returns the wrong value if the array is
#     already populated which is interpreted as an allocation failure. Dave
#     reported this fixes his problem and it also passed a test running dbench
#     over NFS.
#
