Subject: fs: add new FMODE flags: FMODE_32bithash and FMODE_64bithash
X-Git-Tag: MMI-PSA29.97-13-9~17122^2~17^2~3

fs: add new FMODE flags: FMODE_32bithash and FMODE_64bithash

Those flags are supposed to be set by NFS readdir() to tell ext3/ext4
to 32bit (NFSv2) or 64bit hash values (offsets) in seekdir().
