This patch reverts the following three commits which convert libata to use block layer tagging. 43a49cbd e013e13b 2fca5ccf Although using block layer tagging is the right direction, due to the tight coupling among tag number, data structure allocation and hardware command slot allocation, libata doesn't work correctly with the current conversion. The biggest problem is guaranteeing that tag 0 is always used for non-NCQ commands. Due to the way blk-tag is implemented and how SCSI starts and finishes requests, such guarantee can't be made. I'm not sure whether this would actually break any low level driver but it doesn't look like a good idea to break such assumption given the frailty of ATA controllers. So, for the time being, keep using the old dumb in-libata qc allocation. Signed-off-by:

The "Exclude staging drivers" question is there so that we don't build staging drivers for allyesconfig or allnoconfig settings, but it's very irritating when you've already said "no" to staging drivers earlier. There is absolutely no point in declining twice - once you've declined the staging drivers, you're done. So make the second question depend on the first question having been answered in the affirmative. Signed-off-by:

Commit 8d7c4203 "nfsd: fix failure to set eof in readdir in some situations" introduced a bug: on a directory in an exported ext3 filesystem with dir_index unset, a READDIR will only return about 250 entries, even if the directory was larger. Bisected it back to this commit; reverting it fixes the problem. It turns out that in this case ext3 reads a block at a time, then returns from readdir, which means we can end up with buf.full==0 but with more entries in the directory still to be read. Before 8d7c4203 (but after c002a6c7 "Optimise NFS readdir hack slightly"), this would cause us to return the READDIR result immediately, but with the eof bit unset. That could cause a performance regression (because the client would need more roundtrips to the server to read the whole directory), but no loss in correctness, since the cleared eof bit caused the client to send another readdir. After 8d7c4203, the setting of the eof bit made this a correctness problem. So, move nfserr_eof into the loop and remove the buf.full check so that we loop until buf.used==0. The following seems to do the right thing and reduces the network traffic since we don't return a READDIR result until the buffer is full. Tested on an empty directory & large directory; eof is properly sent and there are no more short buffers. Signed-off-by:

Previously I assumed that the receive queues of candidates don't change during the GC. This is only half true, nothing can be received from the queues (see comment in unix_gc()), but buffers could be added through the other half of the socket pair, which may still have file descriptors referring to it. This can result in inc_inflight_move_tail() erronously increasing the "inflight" counter for a unix socket for which dec_inflight() wasn't previously called. This in turn can trigger the "BUG_ON(total_refs < inflight_refs)" in a later garbage collection run. Fix this by only manipulating the "inflight" counter for sockets which are candidates themselves. Duplicating the file references in unix_attach_fds() is also needed to prevent a socket becoming a candidate for GC while the skb that contains it is not yet queued. Reported-by:

Currently, all existing users of cnt32_to_63() are fine since the CPU architectures where it is used don't do read access reordering, and user mode preemption is disabled already. It is nevertheless a good idea to better elaborate usage requirements wrt preemption, and use an explicit memory barrier on SMP to avoid different CPUs accessing the counter value in the wrong order. On UP a simple compiler barrier is sufficient. Signed-off-by:

currently, the error message when trying to run hdspmixer or hdspconf if the breakout box is not connected is somehow misleading, since it asks the user to upload the firmware. this patch adds a test, whether the breakout box is connected and tries to upload the firmware in the case, that it is not present, e.g. because of power failures of the breakout box.

Fix the __pfn_to_page(pfn) macro so that it doesn't evaluate its argument twice in the CONFIG_DISCONTIGMEM=y case, because 'pfn' may be a result of a funtion call having side effects. For example, the hibernation code applies pfn_to_page(pfn) to the result of a function returning the pfn corresponding to the next set bit in a bitmap and the current bit position is modified on each call. This leads to "interesting" failures for CONFIG_DISCONTIGMEM=y due to the current behavior of __pfn_to_page(pfn). Signed-off-by:

But sched_clock() is not a precise clock in the GTOD sense, using such barriers is completely pointless. So remove the barriers and only use them in vget_cycles().
