Hi,
Following patches debloat drivers/scsi/aic7xxx/*. I also had to add prototypes for ahc_lookup_scb and ahd_lookup_scb to .h files.
1-debloat.patch Deinlines and moves big functions from .h to .c files. Adds prototypes for ahc_lookup_scb and ahd_lookup_scb to .h files.
2-addstatic.patch Adds statics, #ifdefs out huge amount of unused code, adds consts
3-addconst.patch Adds more consts
Driver code/data size reductions:
Build with debugging on (CONFIG_AIC7XXX_DEBUG_ENABLE=y): text data bss dec hex filename 310865 49922 1204 361991 58607 linux-2.6.23.t/drivers/scsi/aic7xxx/built-in.o 221987 2754 1204 225945 37299 linux-2.6.23-aic-3-addconst.t/drivers/scsi/aic7xxx/built-in.o
With debugging off: text data bss dec hex filename 298896 42754 1172 342822 53b26 linux-2.6.23.tt/drivers/scsi/aic7xxx/built-in.o 216068 2754 1172 219994 35b5a linux-2.6.23-aic-3-addconst.tt/drivers/scsi/aic7xxx/built-in.o
make namespacecheck goes from 400+ functions to: drivers/scsi/aic7xxx/aic79xx_core.o ahd_inq ahd_inw ahd_outq ahd_outw drivers/scsi/aic7xxx/aic79xx_osm.o ahd_insb drivers/scsi/aic7xxx/aic7xxx_core.o ahc_inq ahc_outq drivers/scsi/aic7xxx/aic7xxx_osm.o ahc_insb
None of these patches touch any logic, code changes are pretty minimal.
Compile tested and applies cleanly to 2.6.23. I don't have this hardware anymore and cannot run test these patches.
Please apply.
