H A D | sb.c | fd615005 Fri Sep 07 07:36:29 CDT 2018 Sascha Hauer <s.hauer@pengutronix.de> ubifs: Store read superblock node
The superblock node is read/modified/written several times throughout the UBIFS code. Instead of reading it from the device each time just keep a copy in memory and write back the modified copy when necessary. This patch helps for authentication support, here we not only have to read the superblock node, but also have to authenticate it, which is easier if we do it once during initialization.
