From 98bdb0aa007ff7e8e0061936d8d0e210faf2e655 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 25 Jan 2011 08:17:48 -0800 Subject: [PATCH 01/61] libceph: fix socket read error handling If we get EAGAIN when trying to read from the socket, it is not an error. Return 0 from the helper in this case to simplify the error handling cases in the caller (indirectly, try_read). Fix try_read to pass any error to it's caller (con_work) instead of almost always returning 0. This let's us respond to things like socket disconnects.

This meant we did it twice for some realms. Which in turn meant we corrupted mdsc->snap_flush_list when the cap_snap was re-added to the list it was already on, and could trigger an infinite loop. We were also using recursion to do reach all the children, a no-no when stack is limited. Instead, (re)queue any children on the dirty list, avoiding processing anything twice and avoiding any recursion.

This is completely bogus. #1) The changelog does not match the patch at all #2) This driver relies on the assumption that it sits behind an eoi capable interrupt line. If the implementation of the underlying chip changes from eoi to irq_eoi then this driver has to follow that change and not add a total bogosity. Remove the sillyness and retrieve the interrupt data from irq_desc directly. No need to got through circles to look it up.

It then ignores that buffer, and passes 'pct' to simple_strtoul(), which doesn't work right because we're comparing 'endp' against a completely different string. Fix it by passing the correct pointer. While we're at it, this is a good candidate for conversion to strict_strtoul as well.

This is a plain x86 IOAPIC interrupt which is handled by the core code perfectly fine. There is nothing special about demultiplexing these gpio interrupts which justifies a custom hack. Replace it by a plain old interrupt handler installed with request_irq. That makes the code agnostic about the underlying primary interrupt hardware. The overhead for this is minimal, but it gives us the advantage of accounting, balancing and to detect interrupt storms. gpio interrupts are not really that performance critical.

This causes wrong backlight values in certain conditions. Instead of adding tricky code handling badly documented and rare corner cases, don't handle combination mode specially at all. This way PCI_LBPC is never touched and weird things shouldn't happen. If combination mode is enabled, then the only downside is that changing the brightness has a greater granularity (the LBPC value), but LBPC is at most 254 and the maximum is in the thousands, so this is no real functional loss. A potential problem with not handling combined mode is that a brightness of max * PCI_LBPC is not bright enough. However, this is very unlikely because from the documentation LBPC seems to act as a scaling factor and doesn't look like it's supposed to be changed after boot. The value at boot should always result in a bright enough screen. IMPORTANT: However, although usually the above is true, it may not be when people ran an older (2.6.37) kernel which messed up the LBPC register, and they are unlucky enough to have a BIOS that saves and restores the LBPC value. Then a good kernel may seem to not work: Max brightness isn't bright enough. If this happens people should boot back into the old kernel, set brightness to the maximum, and then reboot. After that everything should be fine. For more information see the below links.
