ima: remove unnecessary i_mutex locking from ima_rdwr_violation_check()
Before 2.6.39 inode->i_readcount was maintained by IMA. It was not atomic and protected using spinlock. For 2.6.39, i_readcount was converted to atomic and maintaining was moved VFS layer. Spinlock for some unclear reason was replaced by i_mutex. After analyzing the code, we came to conclusion that i_mutex locking is unnecessary, especially when an IMA policy has not been defined. This patch removes i_mutex locking from ima_rdwr_violation_check(). Signed-off-by: Dmitry Kasatkin <d.kasatkin@samsung.com> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
