WebReleasing Locks: When an F_SETLK or F_SETLKW request is made to unlock a byte region of a file, all locks held by that process within the specified region are released. In other words, each byte specified on an unlock request is freed from any lock that is held against it by the requesting process. WebThe answer is - Each block is 32 bytes (8 words), so we need 5 offset bits to determine which byte in each block - Direct-mapped => number of sets = number of blocks = 4096 => we need 12 index bits to determine which set => tag bit = 32 - 12 - 5 = 15 For fully associative, the number of set is 1 => no index bit => tag bit = 32 - 0 - 5 = 27 Share
