Bug #3457: ext2fs and UFS: rename that fails after the source reference is taken leaves the filesystem busy
http://bugs.dragonflybsd.org/issues/3457#change-14911

* Author: sigttou
* Status: Resolved
* Priority: Normal
* Category: Kernel
* Target version: 6.6
* Start date: 2026-10-22
----------------------------------------
@rename(2)@ that fails in @ext2_rename()@ or @ufs_rename()@ after the source directory is referenced (@ENOTEMPTY@, or @EACCES@ on the source directory) returns through bad:/out: without releasing @fdvp at . The mount then stays busy:

 mkdir a b; touch b/k; mv a b     (errno 66)
umount: Device busy; vnconfig -u: busy; umount -f recovers

FreeBSD releases @fdvp@ before these paths. The VFS conversion removed that release but did not add one to the error paths.
