2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Eric Paris commit f06dd16a03f6f7f72fab4db03be36e28c28c6fd6 upstream. Currently IMA does not handle failures from dentry_open(). This means that we leave a pointer set to ERR_PTR(errno) and then try to use it just a few lines later in fput(). Oops.
