There was some talk on this list a year or two ago about adding f_op->fgetattr and f_op->fsetattr methods to the VFS file_operations struct. For some reason or another, that was dropped on the floor, but I'd like to pick that back up and discus it once again. In the file-system I'm working on, there is a distinction between stat(2)s done against a pathname and fstat(2)s done against an open file descriptor. The results of the two are expected to differ in some circumstances. Moreover, I'm building this file-system in FUSE, and while I've managed to hack the underlying fuse code to achieve this behavior, it does so at a substantial performance cost. The more 'correct' solution here would be to export an fgetattr/fsetattr interface at VFS layer, then percolate that change up to the FUSE interface.
