This patch updates the SCSI hosts module to use the ida index-management routines to manage its host_no index instead of using an ATOMIC integer. This means that host numbers can now be reclaimed and re-used.
NOTE: it was not feasible to use idr_*() functions instead of ida_*() functions, since using idr_find() without additional locking to find our Scsi_Host structure left a window between idr lookup and host structure deletion that would have required additional locking to close. Changes from v3: - Switched from idr to ida since managing our instance pointer required extra locking Changes from v2 and v1: - First two version used idr instead of ida Lee Duncan (1): SCSI: hosts: update to use ida_simple for host_no management drivers/scsi/hosts.c | 22 ++++++++++++++-------- 1 file changed, 14 insertions(+), 8 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
