Gleb Smirnoff d89862ac87 Make geom_mirror more friendly to SSDs. To properly support TRIM, ... we need to pass BIO_DELETE requests down to providers that support it. Also, we need to announce our support for BIO_DELETE to upper consumer. This requires: - In g_mirror_start() return true for "GEOM::candelete" request. - In g_mirror_init_disk() probe below provider for "GEOM::candelete" attribute, and mark disk with a flag if it does support BIO_DELETE. - In g_mirror_register_request() distribute BIO_DELETE requests only to those disks, that do support it. Note that we announce "GEOM::candelete" as true unconditionally of whether we have TRIM-capable media down below or not. This is made intentionally, because upper consumer (usually UFS) requests the attribite only once at mount time. And if user ever migrates his mirror from HDDs to SSDs, then he/she would get TRIM working without remounting filesystem. Reviewed by: pjd		2012-07-01 15:43:52 +00:00
