Description

XAttrStorage#updateINodeXAttrs modifies the inode's XAttrFeature based on reading its current state. However, the logic for reading current state is incorrect and may instead read the state of the latest snapshot. If xattrs have been changed after creation of that snapshot, then subsequent xattr operations may yield incorrect results.
