Subject: [PATCH] c/r: alloc_pid() should return -ENOMEM on failure
Date: Wed, 19 Aug 2009 12:46:54 -0700	[thread overview]
Message-ID: <20090819194654.GA22851@us.ibm.com> (raw)


The clone_with_pids() patchset changed alloc_pid() to return an error
code in the pointer. alloc_pid() should then return -ENOMEM rather than
NULL when memory allocations fails.
