rwatson 2008-10-05 21:05:20 UTC FreeBSD src repository Modified files: (Branch: RELENG_7) sys/kern uipc_socket.c Log: SVN rev 183633 on 2008-10-05 21:05:20Z by rwatson Merge r183512 from head to stable/7: Various cleanups for soreceive_dgram(): - Update or remove comments that were left over from the original soreceive_generic() implementation. Quite a few were misleading in the context of the new code. - Since soreceive_dgram() has a simpler structure, replace several gotos with a while loop making the invariants more clear. - In the blocking while loop, don't try to handle cases incompatible with the loop invariant (since m is always NULL, don't check for and handle non-NULL). - Don't drop and re-acquire the socket buffer lock unnecessarily after sbwait() returns, which may help reduce lock contention (etc). - Assume PR_ATOMIC since we assert it at the top of the function. Approved by: re (gnn) Revision Changes Path 1.302.2.8 +19 -58 src/sys/kern/uipc_socket.c
