From 6d79cfb36165c33dd1fd9c4d7ca8436d9a78f7ff Mon Sep 17 00:00:00 2001 From: Andrew Deason Date: Wed, 24 Aug 2011 12:30:00 -0500 Subject: [PATCH] ihandle: Actually assert active fdPs are not AVAIL FdHandle_t's that are on the linked list for an associated IHandle_t should not be in the state FD_HANDLE_AVAIL. For the non-PIO case, we assert that this is the case in ih_open (since we assert that if the FdHandle_t is not in INUSE state, then it must be in OPEN state). However, for the PIO case, we were just skipping over any FdHandle_t's that were in the AVAIL state. These should never exist while on that linked list, so assert for the PIO case, as well. In the absence of bugs, there is no functional change here, but it perhaps makes the ih_open loop easier to understand.
