From 08deafddfcb0380787c7239e57d9b68dd2d29afa Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Fri, 28 Feb 2025 17:48:51 -0500 Subject: [PATCH] dlm: fix error if active rsb is not hashed commit a3672304abf2a847ac0c54c84842c64c5bfba279 upstream. If an active rsb is not hashed anymore and this could occur because we releases and acquired locks we need to signal the followed code that the lookup failed. Since the lookup was successful, but it isn't part of the rsb hash anymore we need to signal it by setting error to -EBADR as dlm_search_rsb_tree() does it.
