Hi, Interested by the recent discussions concerning the copy_from_user() function, I browsed the 2.6.11.7 kernel source, and came up with a few questions.
1. Is there any particular reason why __copy_from_user_ll() is currently EXPORT_SYMBOL()ed for i386? At least none of the in-tree modules currently seem to use it, and __copy_from_user() seems like what most would want anyway. If __copy_from_user_ll() is unexported, it looks like we can eliminate the BUG_ON() statement within it. 2. Would it be possible to eliminate the might_sleep() call in copy_from_user()? It seems that, very soon after, the __copy_from_user() macro does another might_sleep(), with very few instructions in between. But there might be some trick here that I'm missing. Please enlighten. :-) -Vadim Lobanov - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
