commit f0393361ecc39685ee02afd7d4364ee97722befd Author: Dimitry Andric <[email protected]> AuthorDate: 2022-08-14 19:27:16 +0000 Commit: Dimitry Andric <[email protected]> CommitDate: 2022-08-21 11:13:31 +0000 Suppress unused variable warning in tcp_stacks's rack.c With clang 15, the following -Werror warning is produced: sys/netinet/tcp_stacks/rack.c:17405:12: error: variable 'outstanding' set but not used [-Werror,-Wunused-but-set-variable] uint32_t outstanding; ^ The 'outstanding' variable was used later in the rack_output() function, but refactoring in 35c7bb340788f removed the usage. To avoid too much code churn, mark the variable unused to supress the warning.
