Actually, we want to write
some stats info to compactflash. The code is below:
fs =
get_fs();
set_fs(get_ds());
if((tfd = sys_open("/dev/hda2", O_WRONLY, S_IRWXU)) < 0) {
printk("Unable to open stats file to write\n");
} else {
filp = fget(tfd);
write_sizef = (sizeof(flash_stats_info_t)
+ (wear_planes * sizeof(aesop_flash_blk_t))
+ (wear_planes * sizeof(int)));
set_fs(get_ds());
if((tfd = sys_open("/dev/hda2", O_WRONLY, S_IRWXU)) < 0) {
printk("Unable to open stats file to write\n");
} else {
filp = fget(tfd);
write_sizef = (sizeof(flash_stats_info_t)
+ (wear_planes * sizeof(aesop_flash_blk_t))
+ (wear_planes * sizeof(int)));
rbytes = filp->f_op->write(filp,
(char*)(wstats_mem),
write_sizef, &filp->f_pos);
fput(filp);
sys_close(tfd);
}
set_fs(fs);
write_sizef, &filp->f_pos);
fput(filp);
sys_close(tfd);
}
set_fs(fs);

lot.
you should fix the module to not use sys_open; it's been deprecated
for
a LOOOONG time.
can you post the (full) sourcecode for the module
so that we can do
suggestions on how to fix it ?
