aufs: dirren 4/6, rename with saving the rename info · 39d4a736

J. R. Okajima authored Jul 25, 2017



When DIRREN is enabled and activated, the error case where
aufs rename(2) used to return EXDEV will be gone.
Aufs rename(2) registers the renaming dir inum to the list in the
branch, creates the detailed info file, and returns a success.

If udba=notify option is specified with dirren, the internal detection
may not work correctly since aufs may not be able to find the target
name.

DIRREN gives an identifier to every branch, and it is used as a part of
the filename of the detailed info file.

aufs: dirren 1/6, inum-list of the renamed dir in a branch · 53c63b41

J. R. Okajima authored Jul 25, 2017



This commits brings a list of the inode numbers which indicates the
logically renamed dir into a branch. The list will be referred in
lookup, and its lifetime is equivalent to the branch's, ie. the list is
loaded/created in adding a branch, and stored/deleted in deleting a
branch. The simple storing happens in remounting and unmounting aufs
too.
