Subject: [PATCH][1/2] NFS2: Calculate 'w' a bit later in nfsaclsvc_encode_getaclres()
Date: Tue, 21 Nov 2006 12:34:13 +0100 [thread overview]
Message-ID: <200611211234.14027.jesper.juhl@gmail.com> (raw)
NFS2: Calculate 'w' a bit later in nfsaclsvc_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
2406 212 0 2618 a3a fs/nfsd/nfs2acl.o
After:
text data bss dec hex filename
2400 212 0 2612 a34 fs/nfsd/nfs2acl.o
