This patch updates the SCSI hosts module to use the idr 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. It also updates the hosts module to use the idr routine idr_find() to lookup hosts based on the host number, hopefully speeding up said lookup. After noticing that my idr calling sequences where very close to those in other modules, I considered creating some idr helper functions (and using them), but because idr usage almost always requires the caller to manage their own locks, I gave up on this approach (as suggested by Tejon -- thank you). Changes from v1: - no longer using helper routines Changes from v2: - added back missing scsi_host_get() in scsi_host_lookup() Lee Duncan (1): SCSI: update hosts module to use idr index management drivers/scsi/hosts.c | 61 ++++++++++++++++++++++++++-------------------------- 1 file changed, 31 insertions(+), 30 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
