Pull overlayfs updates from Miklos Szeredi: - Report constant st_ino values across copy-up even if underlying layers are on different filesystems, but using different st_dev values for each layer. Ideally we'd report the same st_dev across the overlay, and it's possible to do for filesystems that use only 32bits for st_ino by unifying the inum space. It would be nice if it wasn't a choice of 32 or 64, rather filesystems could report their current maximum (that could change on resize, so it wouldn't be set in stone). - miscellaneus fixes and a cleanup of ovl_fill_super(), that was long overdue. - created a path_put_init() helper that clears out the pointers after putting the ref. I think this could be useful elsewhere, so added it to <linux/path.h> * 'overlayfs-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: (30 commits) ovl: remove unneeded arg from ovl_verify_origin() ovl: Put upperdentry if ovl_check_origin() fails ovl: rename ufs to ofs ovl: clean up getting lower layers ovl: clean up workdir creation ovl: clean up getting upper layer ovl: move ovl_get_workdir() and ovl_get_lower_layers() ovl: reduce the number of arguments for ovl_workdir_create() ovl: change order of setup in ovl_fill_super() ovl: factor out ovl_free_fs() helper ovl: grab reference to workbasedir early ovl: split out ovl_get_indexdir() from ovl_fill_super() ovl: split out ovl_get_lower_layers() from ovl_fill_super() ovl: split out ovl_get_workdir() from ovl_fill_super() ovl: split out ovl_get_upper() from ovl_fill_super() ovl: split out ovl_get_lowerstack() from ovl_fill_super() ovl: split out ovl_get_workpath() from ovl_fill_super() ovl: split out ovl_get_upperpath() from ovl_fill_super() ovl: use path_put_init() in error paths for ovl_fill_super() vfs: add path_put_init() ... |
