fs: xfs: libxfs: constify xfs_nameops structures
Declare the structure xfs_nameops as const as it is only stored in the m_dirnameops field of a xfs_mount structure. This field is of type const struct xfs_nameops *, so xfs_nameops structures having this property can be declared as const. Done using Coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct xfs_nameops i@p = {...}; @ok1@ identifier r1.i; position p; struct xfs_mount mp; @@ mp.m_dirnameops=&i@p @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ static +const struct xfs_nameops i={...}; @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct xfs_nameops i; File size before: text data bss dec hex filename 5302 85 0 5387 150b fs/xfs/libxfs/xfs_dir2.o File size after: text data bss dec hex filename 5318 69 0 5387 150b fs/xfs/libxfs/xfs_dir2.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
