Description

In the Linux kernel, the following vulnerability has been resolved:

ext4: goto right label 'out_mmap_sem' in ext4_setattr()

Otherwise, if ext4_inode_attach_jinode() fails, a hung task will happen because filemap_invalidate_unlock() isn't called to unlock mapping->invalidate_lock. Like this:
