tcp: correct memory barrier usage in tcp_check_space()
[ Upstream commit 56d806222ace4c3aeae516cd7a855340fb2839d8 ]
sock_reset_flag() maps to __clear_bit() not the atomic version clear_bit().
Thus, we need smp_mb(), smp_mb__after_atomic() is not sufficient.
Fixes: 3c7151275c0c ("tcp: add memory barriers to write space paths")
