[PATCH] knfsd: Correct reserved reply space for read requests.
NFSd makes sure there is enough space to hold the maximum possible reply before accepting a request. The units for this maximum is (4byte) words. However in three places, particularly for read request, the number given is a number of bytes. This means too much space is reserved which is slightly wasteful. This is the sort of patch that could uncover a deeper bug, and it is not critical, so it would be best for it to spend a while in -mm before going in to mainline. (akpm: target 2.6.17-rc2, 2.6.16.3 (approx)) Discovered-by: "Eivind Sarto" <ivan@kasenna.com> Signed-off-by: Neil Brown <neilb@suse.de> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
