Don Becker has some text at:

which includes a section:

So I grepped drivers/*/*.c in the nearest handy kernel source, which happened to be 2.2.16, and found 113 uses of SA_INTEERUPT, 64 in drivers/scsi/*.c and the rest spread around.
Do we have a problem? Should it be fixed as part of the cleanup before 2.4.0? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
