From e2f0e7307a7fd8b30bff60c4fb17ce23fc0d773b Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Tue, 12 Jun 2012 16:54:16 -0400 Subject: nfsd: add get_uint for u32's commit a007c4c3e943ecc054a806c259d95420a188754b upstream. I don't think there's a practical difference for the range of values these interfaces should see, but it would be safer to be unambiguous. Signed-off-by: J.
