168 * The following rfs4_fattr4_* functions convert between the fattr4
169 * arguments/attributes and the system (e.g. vattr) values. The following
170 * commands are currently in use:
171 *
172 * NFS4ATTR_SUPPORTED: checks if the attribute in question is supported:
173 * sarg.op = SUPPORTED - all supported attrs
174 * sarg.op = GETIT - only supported readable attrs
175 * sarg.op = SETIT - only supported writable attrs
176 *
177 * NFS4ATTR_GETIT: getattr type conversion - convert system values
178 * (e.g. vattr struct) to fattr4 type values to be returned to the
179 * user - usually in response to nfsv4 getattr request.
180 *
181 * NFS4ATTR_SETIT: convert fattr4 type values to system values to use by
182 * setattr. Allows only read/write and write attributes,
183 * even if not supported by the filesystem. Note that ufs only allows setattr
184 * of owner/group, mode, size, atime/mtime.
185 *
186 * NFS4ATTR_VERIT: convert fattr4 type values to system values to use by
187 * verify/nverify. Implemented to allow
188 * almost everything that can be returned by getattr into known structs
189 * (like vfsstat64 or vattr_t), that is, both read only and read/write attrs.
190 * The function will return -1 if it found that the arguments don't match.
191 * This applies to system-wide values that don't require a fop_getattr
192 * or other further checks to verify. It will return no error if they
193 * either match or were retrieved successfully for later checking.
194 *
195 * NFS4ATTR_FREEIT: free up any space allocated by either of the above.
196 * The sargp->op should be either NFS4ATTR_GETIT or NFS4ATTR_SETIT
197 * to indicate which op was used to allocate the space.
198 *
199 * XXX Note: these functions are currently used by the server only. A
200 * XXX different method of conversion is used on the client side.
201 * XXX Eventually combining the two (possibly by adding NFS4ATTR_CLNT_GETIT
202 * XXX and SETIT) may be a cleaner approach.
