+Subject: ext4: fix special inode number checks in __ext4_iget()
+
+From: Theodore Ts'o <tytso@mit.edu>
+
+commit 191ce17876c9367819c4b0a25b503c0f6d9054d8 upstream.
+
+The check for special (reserved) inode number checks in __ext4_iget()
+was broken by commit 8a363970d1dc: ("ext4: avoid declaring fs
+inconsistent due to invalid file handles").  This was caused by a
+botched reversal of the sense of the flag now known as
+EXT4_IGET_SPECIAL (when it was previously named EXT4_IGET_NORMAL).
+Fix the logic appropriately.
+
+Fixes: 8a363970d1dc ("ext4: avoid declaring fs inconsistent...")
