| D | overlayfs.rst | 148 A whiteout is created as a character device with 0/0 device number or
149 as a zero-size regular file with the xattr "trusted.overlay.whiteout".
151 When a whiteout is found in the upper level of a merged directory, any
152 matching name in the lower level is ignored, and the whiteout itself
161 "trusted.overlay.whiteout", should be additionally marked by setting the xattr
163 This is needed to avoid the overhead of checking the "trusted.overlay.whiteout"
545 A lower dir with a regular whiteout will always be handled by the overlayfs
546 mount, so to support storing an effective whiteout file in an overlayfs mount an
547 alternative form of whiteout is supported. This form is a regular, zero-size
548 file with the "overlay.whiteout" xattr set, inside a directory with the
