5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 53afec2c8fb2a562222948cb1c2aac48598578c9 ]

The help message incorrectly listed '-t' as the short option for --threads, but the actual getopt_long configuration uses '-e'. This mismatch can confuse users and lead to incorrect command-line usage. This patch updates the usage string to correctly show: "-e, --threads NRTHR" to match the implementation.

Note: checkpatch.pl reports a false-positive spelling warning on 'Run', which is intentional.
