From: Theodore Ts'o Date: Mon, 1 Aug 2016 03:38:36 +0000 (-0400) Subject: ext4: reserve xattr index for the Hurd X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3980bd3b406addb327d858aebd19e229ea340b9a;p=linux-beck.git ext4: reserve xattr index for the Hurd The Hurd is using inode fields which restricts it from using more advanced ext4 file system features, due to design choices made over a decade ago. By giving the Hurd an extended attribute index field we allow it to move the translator and author fields out of the core inode fields, and hopefully we can get rid of ugly hacks such as EXT4_OS_HURD and EXT4_MOUNT2_HURD_COMPAT somday.
