From a39dd4a8a2667a356076c964a98d206994042433 Mon Sep 17 00:00:00 2001 From: iedowse Date: Wed, 1 Aug 2001 10:25:13 +0000 Subject: Fix a client-side memory leak in nfs_flush(). The code allocates a temporary array to store struct buf pointers if the list doesn't fit in a local array. Usually it frees the array when finished, but if it jumps to the 'again' label and the new list does fit in the local array then it can forget to free a previously malloc'd M_TEMP memory. Move the free() up a line so that it frees any previously allocated memory whether or not it needs to malloc a new array.
