I'm getting an oops when running mkfs on zram: NIP [d0000000030e0340] .zram_inc_stat+0x58/0x84 [zram] [c00000006d58f720] [d0000000030e091c] .zram_make_request+0xa8/0x6a0 [zram] [c00000006d58f840] [c00000000035795c] .generic_make_request+0x390/0x434 [c00000006d58f950] [c000000000357b14] .submit_bio+0x114/0x140 [c00000006d58fa20] [c000000000361778] .blkdev_issue_discard+0x1ac/0x250 [c00000006d58fb10] [c000000000361f68] .blkdev_ioctl+0x358/0x7fc [c00000006d58fbd0] [c0000000001c1c1c] .block_ioctl+0x6c/0x90 [c00000006d58fc70] [c0000000001984c4] .do_vfs_ioctl+0x660/0x6d4 [c00000006d58fd70] [c0000000001985a0] .SyS_ioctl+0x68/0xb0 Since disksize no longer starts as 0 it looks like we can call zram_make_request before the device has been initialised. The patch below fixes the immediate problem but this would go away if we move the initialisation function elsewhere (as suggested in another thread).
