  [PATCH] ubifs: Don't block RENAME_WHITEOUT flag in rename Jesper Nilsson <jesper.nilsson@axis.com> - 2017-03-29 17:20 +0200

#1612031 — [PATCH] ubifs: Don't block RENAME_WHITEOUT flag in rename

The test does not allow the valid flag RENAME_WHITEOUT
and in fact, the calling function of do_rename already tests
the flags, so the test is unnecessary, allowing us to drop
it completely.

With this patch RENAME_WHITEOUT for overlayfs on ubifs works
as intended.
