| |
2.6.29-stable review patch. If anyone has any objections, please let us know.
------------------
From: "Theodore Ts'o" <tytso@mit.edu>
(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.
