@ -145,7 +145,9 @@ filesystem, an overlay filesystem needs to record in the upper filesystem
that files have been removed. This is done using whiteouts and opaque
directories (non-directories are always opaque).
A whiteout is created as a character device with 0/0 device number.
A whiteout is created as a character device with 0/0 device number or
as a zero-size regular file with the xattr "trusted.overlay.whiteout".
When a whiteout is found in the upper level of a merged directory, any
matching name in the lower level is ignored, and the whiteout itself
is also hidden.
@ -154,6 +156,13 @@ A directory is made opaque by setting the xattr "trusted.overlay.opaque"
to "y". Where the upper filesystem contains an opaque directory, any
directory in the lower filesystem with the same name is ignored.
An opaque directory should not conntain any whiteouts, because they do not
serve any purpose. A merge directory containing regular files with the xattr
"trusted.overlay.whiteout", should be additionally marked by setting the xattr
"trusted.overlay.opaque" to "x" on the merge directory itself.
This is needed to avoid the overhead of checking the "trusted.overlay.whiteout"
on all entries during readdir in the common case.

@ -534,8 +543,9 @@ A lower dir with a regular whiteout will always be handled by the overlayfs
mount, so to support storing an effective whiteout file in an overlayfs mount an
alternative form of whiteout is supported. This form is a regular, zero-size
file with the "overlay.whiteout" xattr set, inside a directory with the
"overlay.whiteouts" xattr set. Such whiteouts are never created by overlayfs,
but can be used by userspace tools (like containers) that generate lower layers.
"overlay.opaque" xattr set to "x" (see `whiteouts and opaque directories`_).
These alternative whiteouts are never created by overlayfs, but can be used by
userspace tools (like containers) that generate lower layers.
These alternative whiteouts can be escaped using the standard xattr escape
mechanism in order to properly nest to any depth.
