Vulnerability from github
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:
EXT4-fs error (device sda) in ext4_setattr:5557: Out of memory INFO: task fsstress:374 blocked for more than 122 seconds.
