Thank you for your advice. That's a great idea.
I'm about to send a patch v3 with the changes suggested by you.
Best Regards

Using list_move_tail() instead of list_del() + list_add_tail() in atomisp_compat_css20.c.
Have you considered using list_splice() instead of entire while-loops?
Or something similar from list.h...
while (!list_empty(&asd->s3a_stats_in_css)) {
s3a_buf = list_entry(asd->s3a_stats_in_css.next,
struct atomisp_s3a_buf, list);
- list_del(&s3a_buf->list);
- list_add_tail(&s3a_buf->list, &asd->s3a_stats);
+ list_move_tail(&s3a_buf->list, &asd->s3a_stats);
}
while (!list_empty(&asd->s3a_stats_ready)) {
s3a_buf = list_entry(asd->s3a_stats_ready.next,
struct atomisp_s3a_buf, list);
- list_del(&s3a_buf->list);
- list_add_tail(&s3a_buf->list, &asd->s3a_stats);
+ list_move_tail(&s3a_buf->list, &asd->s3a_stats);
}
while (!list_empty(&asd->dis_stats_in_css)) {
dis_buf = list_entry(asd->dis_stats_in_css.next,
struct atomisp_dis_buf, list);
- list_del(&dis_buf->list);
- list_add_tail(&dis_buf->list, &asd->dis_stats);
+ list_move_tail(&dis_buf->list, &asd->dis_stats);
}
while (!list_empty(&asd->metadata_in_css[i])) {
md_buf = list_entry(asd->metadata_in_css[i].next,
struct atomisp_metadata_buf, list);
- list_del(&md_buf->list);
- list_add_tail(&md_buf->list, &asd->metadata[i]);
+ list_move_tail(&md_buf->list, &asd->metadata[i]);
}
while (!list_empty(&asd->metadata_ready[i])) {
md_buf = list_entry(asd->metadata_ready[i].next,
struct atomisp_metadata_buf, list);
- list_del(&md_buf->list);
- list_add_tail(&md_buf->list, &asd->metadata[i]);
+ list_move_tail(&md_buf->list, &asd->metadata[i]);
}
