 Modified Files:
 	src/sys/fs/tmpfs: tmpfs.h tmpfs_subr.c tmpfs_vnops.c
 
 Log Message:
 Truncate directory cookies to 31 bits to avoid problems exposed in Linux
 binaries which cast the returned values to 64-bits and fail due to sign
 expansion.  More details are provided in the big comment in tmpfs.h that
 describes how the new tmpfs_dircookie works.
 
 This is a rather ugly hack that shall be fixed with a cleaner solution,
 but this resolves the problem in an effective way.
 
 Fixes kern PR/32034.
