If anyone has any objections, please let me know. ------------------ From: Mike Marciniszyn commit eefa1d8961584c5b76afded94960ca4344bc638b upstream. The __must_hold() is sufficent to correct the sparse context imbalance inside a function. Per Documentation/sparse.txt: __must_hold - The specified lock is held on function entry and exit.
