From 2b111edbe0a9c441605be5cfb73001dc98ec686f Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Fri, 23 Aug 2024 14:47:40 +0200 Subject: [PATCH] inode: make i_state a u32 Now that we use the wait var event mechanism make i_state a u32 and free up 4 bytes. This means we currently have two 4 byte holes in struct inode which we can pack.
