From 6982100bb8297c46122cac4f684dcf44cb7d0d8c Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Tue, 29 Apr 2025 15:42:53 +0200 Subject: [PATCH] zonefs: use ZONEFS_SUPER_SIZE instead of PAGE_SIZE Use ZONEFS_SUPER_SIZE constant instead of PAGE_SIZE allocating memory for reading the super block in zonefs_read_super(). While PAGE_SIZE technically isn't incorrect as Linux doesn't support pages smaller than 4k ZONEFS_SUPER_SIZE is semantically more correct. Signed-off-by: Johannes Thumshirn Reviewed-by: "Darrick J.
