Subject: nfsd41: add OPEN4_SHARE_ACCESS_WANT nfs4_stateid bmap
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=84459a1162801fb84734e5f9e6dc5194f791d69b;p=deliverable%2Flinux.git

nfsd41: add OPEN4_SHARE_ACCESS_WANT nfs4_stateid bmap

Separate the access bits from the want bits and enable __set_bit to
work correctly with st_access_bmap.
