Olivier Houchard a7bf573520 MEDIUM: fd: Introduce a running mask, and use it instead of the spinlock. ... In the struct fdtab, introduce a new mask, running_mask. Each thread should add its bit before using the fd. Use the running_mask instead of a lock, in fd_insert/fd_delete, we'll just spin as long as the mask is non-zero, to be sure we access the data exclusively. fd_set_running_excl() spins until the mask is 0, fd_set_running() just adds the thread bit, and fd_clr_running() removes it.		2020-03-17 15:30:07 +01:00
