I run the code below but VOP_PUTPAGES never return anything else than 0.
int
puffs_gop_alloc(struct vnode *vp, off_t off, off_t len,
int flags, kauth_cred_t cred)
{
struct puffs_mount *pmp = MPTOPUFFSMP(vp->v_mount);
off_t start, end;
int pgo_flags = PGO_CLEANIT|PGO_SYNCIO|PGO_PASTEOF;
int u_flags = PUFFS_UPDATESIZE|PUFFS_UPDATEMTIME|PUFFS_UPDATECTIME;
int error;
if (EXISTSOP(pmp, FALLOCATE)) {
error = _puffs_vnop_fallocate(vp, off, len);
goto out;
}
start = trunc_page(off);
end = round_page(off + len);
if (off + len > vp->v_size)
uvm_vnp_setwritesize(vp, off + len);
mutex_enter(vp->v_interlock);
error = VOP_PUTPAGES(vp, start, end, pgo_flags);
if (off + len > vp->v_size) {
if (error == 0) {
uvm_vnp_setsize(vp, off + len);
puffs_updatenode(VPTOPP(vp), u_flags, vp->v_size);
} else {
uvm_vnp_setwritesize(vp, vp->v_size);
}
}
out:
return error;
}
