From 1fc98d11cac6dd66342e5580cb2687e5b1e9a613 Mon Sep 17 00:00:00 2001 From: Andrey Vagin Date: Tue, 9 Sep 2014 14:51:04 -0700 Subject: fsnotify/fdinfo: use named constants instead of hardcoded values MAX_HANDLE_SZ is equal to 128, but currently the size of pad is only 64 bytes, so exportfs_encode_inode_fh can return an error.
