Log Message:
-----------
igrab returns NULL when the inode state is (I_FREEING|I_CLEAR|I_WILL_FREE). Check the return value of VN_HOLD (igrab), if it is NULL then return an error EAGAIN.
- When the system is running short of memory, various caches (inode and/or dentry) are shrinked to make more memory available. The patch ensures the inode being used is not either, in state of being freed (I_FREEING or I_WILL_FREE) or freed (I_CLEAR).
