also note that in include/linux/ide.h:883:
typedef int (ide_expiry_t)(ide_drive_t *);
doesn't this mean that expiry returns int, and wait therefore should be int as well?
It does... and it seems like it could cause insanely long timeouts for:
* ATA_DMA_ERR error in dma_timer_expiry()
* commands without ->expiry in tc86c001_timer_expiry() (TC86C001 IDE controller only)
This is 2.6.29 material, care to make a patch?
Er, it's not that bad as it gets cast back to *int* when calling ide_dma_timer_expiry().
Thanks, Bart
