[PATCH] NFS3: Calculate 'w' a bit later in nfs3svc_encode_getaclres()
NFS3: Calculate 'w' a bit later in nfs3svc_encode_getaclres()
This is a small performance optimization since we can return before
needing 'w'. It also saves a few bytes of .text :
Before:
text data bss dec hex filename
1632 140 0 1772 6ec fs/nfsd/nfs3acl.o
After:
text data bss dec hex filename
1624 140 0 1764 6e4 fs/nfsd/nfs3acl.o
