commit aff3bea95388299eec63440389b4545c8041b357
Author: Theodore Ts'o <tytso@mit.edu>
Date:   Tue May 23 23:49:51 2023 -0400

    ext4: add lockdep annotations for i_data_sem for ea_inode's
    
    Treat i_data_sem for ea_inodes as being in their own lockdep class to
    avoid lockdep complaints about ext4_setattr's use of inode_lock() on
    normal inodes potentially causing lock ordering with i_data_sem on
    ea_inodes in ext4_xattr_inode_write().  However, ea_inodes will be
    operated on by ext4_setattr(), so this isn't a problem.
