Eric Biggers 416a5d0346 smack: use GFP_NOFS while holding inode_smack::smk_lock ... commit e5bfad3d7a upstream. inode_smack::smk_lock is taken during smack_d_instantiate(), which is called during a filesystem transaction when creating a file on ext4. Therefore to avoid a deadlock, all code that takes this lock must use GFP_NOFS, to prevent memory reclaim from waiting for the filesystem transaction to complete.
