+Subject: [PATCH] vfs: Fix /proc/<tid>/fdinfo/<fd> file handling
+
+commit 0640113be25d283e0ff77a9f041e1242182387f0 upstream.
+
+Cyrill Gorcunov reports that I broke the fdinfo files with commit
+30a08bf2d31d ("proc: move fd symlink i_mode calculations into
+tid_fd_revalidate()"), and he's quite right.
+
+The tid_fd_revalidate() function is not just used for the <tid>/fd
+symlinks, it's also used for the <tid>/fdinfo/<fd> files, and the
+permission model for those are different.
+
+So do the dynamic symlink permission handling just for symlinks, making
+the fdinfo files once more appear as the proper regular files they are.
+
+Of course, Al Viro argued (probably correctly) that we shouldn't do the
+symlink permission games at all, and make the symlinks always just be
+the normal 'lrwxrwxrwx'.  That would have avoided this issue too, but
+since somebody noticed that the permissions had changed (which was the
+reason for that original commit 30a08bf2d31d in the first place), people
+do apparently use this feature.
+
+[ Basically, you can use the symlink permission data as a cheap "fdinfo"
+  replacement, since you see whether the file is open for reading and/or
+  writing by just looking at st_mode of the symlink.  So the feature
+  does make sense, even if the pain it has caused means we probably
+  shouldn't have done it to begin with. ]
