From 4973b04d3ea577db80c501c5f14e68ec69fe1794 Mon Sep 17 00:00:00 2001 From: Marios Makassikis Date: Mon, 15 Apr 2024 15:12:48 +0200 Subject: ksmbd: clear RENAME_NOREPLACE before calling vfs_rename File overwrite case is explicitly handled, so it is not necessary to pass RENAME_NOREPLACE to vfs_rename. Clearing the flag fixes rename operations when the share is a ntfs-3g mount. The latter uses an older version of fuse with no support for flags in the ->rename op.
