2011-07-22lguest: Simplify device initialization.Rusty Russell1-19/+6
We used to notify the Host every time we updated a device's status. However, it only really needs to know when we're resetting the device, or failed to initialize it, or when we've finished our feature negotiation. In particular, we used to wait for VIRTIO_CONFIG_S_DRIVER_OK in the status byte before starting the device service threads. But this corresponds to the successful finish of device initialization, which might (like virtio_blk's partition scanning) use the device. So we had a hack, if they used the device before we expected we started the threads anyway. Now we hook into the finalize_features hook in the Guest: at that point we tell the Launcher that it can rely on the features we have acked. On the Launcher side, we look at the status at that point, and start servicing the device. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-07-22lguest: Do not exit on non-fatal errorsSakari Ailus1-4/+6
Do not exit on some non-fatal errors: - writev() fails in net_output(). The result is a lost packet or packets. - writev() fails in console_output(). The result is partially lost console output. - readv() fails in net_input(). The result is a lost packet or packets. Rather than bringing the guest down, this patch ignores e.g. an allocation failure on the host side.

All these are instances of #define NAME value; or #define NAME(params_opt) value; These of course fail to build when used in contexts like if(foo $OP NAME) while(bar $OP NAME) and may silently generate the wrong code in contexts such as foo = NAME + 1; /* foo = value; + 1; */ bar = NAME - 1; /* bar = value; - 1; */ baz = NAME & quux; /* baz = value; & quux; */ Reported on comp.lang.c, Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com> Initial analysis of the dangers provided by Keith Thompson in that thread. There are many more instances of more complicated macros having unnecessary trailing semicolons, but this pile seems to be all of the cases of simple values suffering from the problem. (Thus things that are likely to be found in one of the contexts above, more complicated ones aren't.)

2011-07-20fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik3-5/+10
Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

2011-07-20fs: add SEEK_HOLE and SEEK_DATA flagsJosef Bacik1-0/+10
This just gets us ready to support the SEEK_HOLE and SEEK_DATA flags. Turns out using fiemap in things like cp cause more problems than it solves, so lets try and give userspace an interface that doesn't suck. We need to match solaris here, and the definitions are *o* If /whence/ is SEEK_HOLE, the offset of the start of the next hole greater than or equal to the supplied offset is returned. The definition of a hole is provided near the end of the DESCRIPTION. *o* If /whence/ is SEEK_DATA, the file pointer is set to the start of the next non-hole file region greater than or equal to the supplied offset. So in the generic case the entire file is data and there is a virtual hole at the end. That means we will just return i_size for SEEK_HOLE and will return the same offset for SEEK_DATA. This is how Solaris does it so we have to do it the same way. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-07-20vfs: increase shrinker batch sizeDave Chinner1-0/+6
Now that the per-sb shrinker is responsible for shrinking 2 or more caches, increase the batch size to keep econmies of scale for shrinking each cache. Increase the shrinker batch size to 1024 objects. To allow for a large increase in batch size, add a conditional reschedule to prune_icache_sb() so that we don't hold the LRU spin lock for too long. This mirrors the behaviour of the __shrink_dcache_sb(), and allows us to increase the batch size without needing to worry about problems caused by long lock hold times. To ensure that filesystems using the per-sb shrinker callouts don't cause problems, document that the object freeing method must reschedule appropriately inside loops.

2011-07-20superblock: add filesystem shrinker operationsDave Chinner1-0/+16
Now we have a per-superblock shrinker implementation, we can add a filesystem specific callout to it to allow filesystem internal caches to be shrunk by the superblock shrinker. Rather than perpetuate the multipurpose shrinker callback API (i.e. nr_to_scan == 0 meaning "tell me how many objects freeable in the cache), two operations will be added. The first will return the number of objects that are freeable, the second is the actual shrinker call.

2011-07-19ARM: 6999/1: head, zImage: Always Enter the kernel in ARM stateDave Martin1-0/+5
Currently, the documented kernel entry requirements are not explicit about whether the kernel should be entered in ARM or Thumb, leading to an ambiguitity about how to enter Thumb-2 kernels. As a result, the kernel is reliant on the zImage decompressor to enter the kernel proper in the correct instruction set state. This patch changes the boot entry protocol for head.S and Image to be the same as for zImage: in all cases, the kernel is now entered in ARM. Documentation/arm/Booting is updated to reflect this new policy. A different rule will be needed for Cortex-M class CPUs as and when support for those lands in mainline, since these CPUs don't support the ARM instruction set at all: a note is added to the effect that the kernel must be entered in Thumb on such systems.

As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code.

2011-07-15PM / OPP: Introduce function to free cpufreq tableNishanth Menon1-0/+2
cpufreq table allocated by opp_init_cpufreq_table is better freed by OPP layer itself. This allows future modifications to the table handling to be transparent to the users.

2011-07-15tracing/kprobes: Support module init function probingMasami Hiramatsu1-4/+5
To support probing module init functions, kprobe-tracer allows user to define a probe on non-existed function when it is given with a module name. This also enables user to set a probe on a function on a specific module, even if a same name (but different) function is locally defined in another module. The module name must be in the front of function name and separated by a ':'. e.g. btrfs:btrfs_init_sysfs Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Link: http://lkml.kernel.org/r/20110627072656.6528.89970.stgit@fedora15 Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

It turns out that parsing the vDSO is nontrivial if you don't already have an ELF dynamic loader around. So document it in Documentation/ABI and add a reference CC0-licenced parser.
