To: linux-megaraid-devel; +Cc: linux-kernel, linux-scsi
Trying to compile drivers/scsi/megaraid.c with gcc 3.4 and
# define inline __inline__ __attribute__((always_inline))
results in compile errors starting with the following:
<-- snip -->
...
CC drivers/scsi/megaraid.o
drivers/scsi/megaraid.c: In function `megaraid_queue':
drivers/scsi/megaraid.h:1000: sorry, unimplemented: inlining failed in call to 'mega_runpendq': function body not available
drivers/scsi/megaraid.c:379: sorry, unimplemented: called from here
make[2]: *** [drivers/scsi/megaraid.o] Error 1
<-- snip -->
The patch below fixes these issues by:
- removing some inlines
- moving some functions
- replacing free_local_pdev() with calls to kfree()
diffstat output:
