From: David Howells Date: Fri, 11 Mar 2022 13:24:47 +0000 (+0000) Subject: watch_queue: Make comment about setting ->defunct more accurate X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4edc0760412b0c4ecefc7e02cb855b310b122825;p=linux.git watch_queue: Make comment about setting ->defunct more accurate watch_queue_clear() has a comment stating that setting ->defunct to true preventing new additions as well as preventing notifications. Whilst the latter is true, the first bit is superfluous since at the time this function is called, the pipe cannot be accessed to add new event sources. Remove the "new additions" bit from the comment.
