From 28d64a64f5bb17b8dab69366d9fb6930dc93322a Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Tue, 2 Jun 2009 08:09:32 -0400 Subject: [PATCH] ext4: Ignore i_file_acl_high unless EXT4_FEATURE_INCOMPAT_64BIT is present (cherry picked from commit a9e817425dc0baede8ebe5fbc9984a640257432b) Don't try to look at i_file_acl_high unless the INCOMPAT_64BIT feature bit is set. The field is normally zero, but older versions of e2fsck didn't automatically check to make sure of this, so in the spirit of "be liberal in what you accept", don't look at i_file_acl_high unless we are using a 64-bit filesystem.
