Steffen Trumtrar	6561e07460	mount: support the sizelimit and offset option for loop devices Starting with linux kernel v5.4 squashfs has a more strict parameter checking implemented. Unlike util-linux mount, busybox never supported the sizelimit option but simply forwards it to the kernel. Since v5.4 mounting will fail with squashfs: Unknown parameter 'sizelimit' Support the sizelimit parameter by setting it in the LOOP_SET_STATUS64 structure before handing it to the kernel. While at it also add support for the offset option, which currently will always be set to 0. function old new delta cut_out_ull_opt - 167 +167 singlemount 1230 1266 +36 set_loop 834 862 +28 losetup_main 479 483 +4 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 3/0 up/down: 235/0) Total: 235 bytes Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2020-10-01 00:31:11 +02:00
