Subject: rcutorture: Small code cleanups
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=293b93d66f149a9bd124aae195f048268e11870c;p=linux.git

rcutorture: Small code cleanups

The rcu_torture_cleanup() function fails to NULL out the reader_tasks
pointer after freeing it and its fakewriter_tasks loop has redundant
braces.  This commit therefore cleans these up.
