https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260200 --- Comment #6 from Aleksandr Fedorov <afedorov@FreeBSD.org> --- I think the swap backend should also ignore the BIO_FLUSH command. Because = swap is not a persistent storage, I don't know how BIO_FLUSH can be useful. As for ctl(4), it works with SCSI commands. Ramdisk backend simply ignores = the SYNCHRONIZE_CACHE and SYNCHRONIZE_CACHE_16 commands: https://github.com/freebsd/freebsd-src/blob/main/sys/cam/ctl/ctl_backend_ra= mdisk.c#L748 --=20 You are receiving this mail because: You are the assignee for the bug.=
