[PATCH] knfsd: nfsd4: clarify units of COMPOUND_SLACK_SPACE
A comment here incorrectly states that "slack_space" is measured in words, not bytes. Remove the comment, and adjust a variable name and a few comments to clarify the situation. This is pure cleanup; there should be no change in functionality. Signed-off-by: J.
