That would work. A massive thread is easy to delete. Or even just apply them first, and we tell people to send follow on patches or revert as needed. My whole setup revolves around email so finding and reviewing patches using git log is awkward. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I don't think that's necessary, but sending them to any listed maintainer should be. If you're collecting them, I suggest you stick them in a separate branch, post them to your driverdev list and cc the appropriate maintainers, wait a week, then apply them to your main branch.

We don't get many bugs through outreachy, but this isn't the first one.

I'm fine with 5 bugs per 900 patches or whatever. I wish that the

Adding the maintainer to the original list would still be a good step. I'm not
sure that I would have caught "rtl8712: Use memdup_user() instead of
copy_from_user()" in review, but I certainly would have seen that it was not
proper to do a blanket substitution of del_timer_sync() for a wrapper that used
del_timer().
Obviously the awful coding in rtl8712 contains more traps to trick the novices
than does most code. It also predates a lot of changes in checkpatch.pl and
contains a lot of low-hanging fruit.

Hm, I don't know then, but from what I have seen, the tasks that send patches to the kernel are not pre-reviewed by anyone.

Greg,
Please drop this patch. The same fixes were submitted as

It is crucial that this get into the 4.1 kernel where the regression was

Perhaps it could prevent other warnings like this in the future. _cancel_timer and _cancel_timer_ex both were internally using del_timer, and the issue was reported in bugzilla.

I have changed the reference of del_timer_sync to del_timer in all places which were in interrupt context, in some places it was not removed as those were not in interrupt context. Why did you not Cc the maintainers?? That is why file MAINTAINERS exists. Was your patch sent to Greg?

Yes, it was sent during Outreachy process. But it was my mistake as a newbie. May be I should have taken care of interrupt mode thing. I would like to fix it if someone is not doing it. Sorry again. I will take care of these things in my future patches. No, one of us will fix the problems with r8712u. The hardware is needed for proper testing, and I doubt that you have it.

It's Greg's fault for merging these when they weren't sent to the list or to the other maintainers. But Greg knows I'm annoyed already since we have been dealing with the fallout for months and I always make sure to complain whenever I have a chance. /me shakes a fist!

These are special intern patches that dont' go through the normal review process. The intern process is over this year. The lack of normal review introduced a number of bugs this year. I always complain to Greg about it and he says that I should join the intern mailing list if I care so much. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Perhaps it >could prevent other warnings like this in the future. _cancel_timer and _cancel_timer_ex both were internally using del_timer, and the issue was reported in bugzilla. I have given the reference of the bugzilla in my patch in lkml. I have changed the reference of del_timer_sync to del_timer in all places which were in interrupt context, in some places it was not removed as those were not in interrupt context. regards sudip -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH] staging: r8712u: Fix kernel warning for improper call of del_timer_sync()
The driver is reporting a warning at kernel/time/timer.c:1096 due to calling
del_timer_sync() while in interrupt mode. Such warnings are fixed by calling
del_timer() instead.
