aufs: writable branch 1/3, white-out · 72a970fc

J. R. Okajima authored Mar 30, 2015



The writable branch prepares a few files and dirs for whiteouts.
For branch filesystems which doesn't support link(2), there is "nolwh"
attribute. On the branch which is specified this attribute, aufs never
try link(2) for whitout and always creat(2) it.

aufs: white-out 1/2 · 2a7e7277

J. R. Okajima authored Mar 30, 2015



The whiteout represents a logical deletion.
Although the document in this commit mentioned about rmdir(2) and
rename(2) for dir, this commit doesn't contain such functions. They will
be added in later commits.
