Subject: [BUILD FAILURE] nfs4state.c fails to compile with gcc 4.5.4

Just letting you know that this commit:

fcd8843c406 ('NFSv4: Replace closed stateids with the "invalid special
stateid"') causes gcc 4.5.4 to fail the build with this error:

Seems it can't handle the initialization of an anonymous struct within
an anonymous union.

I switched to gcc 4.6.3 and it compiles fine.
