Isn't that the MAX_HWIFS upper bound of a loop.. ? Close, it is related to MAX_HWIFS being upper bound on hws[] in ide_generic.c but now we loop for ARRAY_SIZE(legacy_bases). IOW there is a memset(hws, 0, MAX_HWIFS) missing at the top of ide_generic_init() (please re-test after adding it). This may also explain the later problems with ide_host_register(). > > > From: Borislav Petkov <petkovbb@xxxxxxxxx> > > > > > > Check the correct flags-location for set features. > > > > > > Signed-off-by: Borislav Petkov <petkovbb@xxxxxxxxx> > > > > Thanks, I folded the fix into original patch (->dev_flags is not yet > > upstream so -stable fix shouldn't be necessary). > > > > While on it: I later noticed that there will be also need for common > > ATA/ATAPI ->dev_flags in the future so I wonder whether current > > ->dev_flags should be renamed to ->atapi_flags (& s/*DFLAG*/*AFLAG*/). > > > > If there is agreement on this I'll fix it in pata tree. > > ... or if there's room, use a single ->dev_flags for all possible flag settings? Unfortunately there isn't enough room left (27 bits are occupied ATM) and having u64 ->dev_flags sucks... -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
