File _service:tar_scm_kernel_repo:0042-debugfs-Use-the-hash_version-from-superblock-if-a-fi.patch of Package e2fsprogs
From 29d83fef9e6eab139516afe433c03d975e85c25b Mon Sep 17 00:00:00 2001 From: Srivathsa Dara <srivathsa.d.dara@oracle.com> Date: Thu, 24 Aug 2023 06:56:34 +0000 Subject: [PATCH] debugfs: Use the hash_version from superblock if a file system is opened The debugfs program's dx_hash command computes the hash for the given filename, taking the hash_seed and hash_version (i.e hash algorithm) as arguments. So the user has to refer to the superblock to get these values used by the filesystem. So if debugfs has an opened file system, use those values from the current file system.
