From 6320377fd94316e58f75d0be6f6e7a644950a4ee Mon Sep 17 00:00:00 2001 From: Olaf Kirch Date: Thu, 13 Dec 2007 12:43:25 -0600 Subject: [SCSI] libiscsi, iscsi_tcp: iscsi pool cleanup iscsi_pool_init simplified iscsi_pool_init currently has a lot of duplicate kfree() calls it does when some allocation fails. This patch simplifies the code a little by using iscsi_pool_free to tear down the pool in case of an error. iscsi_pool_init also returns a copy of the item array to the caller. Not all callers use this array, so we make it optional. Instead of allocating a second array and return that, allocate just one array, of twice the size. Update users of iscsi_pool_{init,free} This patch drops the (now useless) second argument to iscsi_pool_free, and updates all callers. It also removes the ctask->r2ts array, which was never used anyway. Since the items argument to iscsi_pool_init is now optional, we can pass NULL instead.
