tmp = atomic_long_fetch_add_release( - On 64-bit architectures, the bit definitions of the count are:* Bit 0 - writer locked bit* Bit 1 - waiters present bit* Bit 2 - lock handoff bit* Bits 3-7 - reserved* Bits 8-62 - 55-bit reader count* Bit 63 - read fail bit* On 32-bit architectures, the , & count)

If Value for the false possibility is greater at compile time(tmp & RWSEM_FLAG_WAITERS) Then handle waking up a waiter on the semaphore* - up_read/up_write has decremented the active part of count if we come here
