# Simple permission check on hard links.

# Overlayfs had a bug that hardlinks don't share inode, if chmod/chown/etc.
|
|
# is performed on one of the links then the inode belonging to the other
|
|
# one won't be updated. The following patch fixed this issue
|
|
#
|
|
# 51f7e52 ovl: share inode for hard link
