2014-06-04f2fs: large volume supportChangman Lee1-0/+2
f2fs's cp has one page which consists of struct f2fs_checkpoint and version bitmap of sit and nat. To support lots of segments, we need more blocks for sit bitmap. So let's arrange sit bitmap as following: +-----------------+------------+ | f2fs_checkpoint | sit bitmap | | + nat bitmap | | +-----------------+------------+ 0 4k N blocks Signed-off-by: Changman Lee <cm224.lee@samsung.com> [Jaegeuk Kim: simple code change for readability] Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
2014-06-04f2fs: avoid overflow when large directory feathure is enabledChao Yu1-0/+3
When large directory feathure is enable, We have one case which could cause overflow in dir_buckets() as following: special case: level + dir_level >= 32 and level < MAX_DIR_HASH_DEPTH / 2. Here we define MAX_DIR_BUCKETS to limit the return value when the condition could trigger potential overflow. Changes from V1 o modify description of calculation in f2fs.txt suggested by Changman Lee.

2014-06-04drm: Split connection_mutex out of mode_config.mutex (v3)Daniel Vetter1-0/+1
After the split-out of crtc locks from the big mode_config.mutex there's still two major areas it protects: - Various connector probe states, like connector->status, EDID properties, probed mode lists and similar information. - The links from connector->encoder and encoder->crtc and other modeset-relevant connector state (e.g. properties which control the panel fitter). The later is used by modeset operations. But they don't really care about the former since it's allowed to e.g. enable a disconnected VGA output or with a mode not in the probed list. Thus far this hasn't been a problem, but for the atomic modeset conversion Rob Clark needs to convert all modeset relevant locks into w/w locks. This is required because the order of acquisition is determined by how userspace supplies the atomic modeset data. This has run into troubles in the detect path since the i915 load detect code needs _both_ protections offered by the mode_config.mutex: It updates probe state and it needs to change the modeset configuration to enable the temporary load detect pipe. The big deal here is that for the probe/detect users of this lock a plain mutex fits best, but for atomic modesets we really want a w/w mutex. To fix this lets split out a new connection_mutex lock for the modeset relevant parts. For simplicity I've decided to only add one additional lock for all connector/encoder links and modeset configuration states. We have piles of different modeset objects in addition to those (like bridges or panels), so adding per-object locks would be much more effort. Also, we're guaranteed (at least for now) to do a full modeset if we need to acquire this lock. Which means that fine-grained locking is fairly irrelevant compared to the amount of time the full modeset will take. I've done a full audit, and there's just a few things that justify special focus: - Locking in drm_sysfs.c is almost completely absent. We should sprinkle mode_config.connection_mutex over this file a bit, but since it already lacks mode_config.mutex this patch wont make the situation any worse. This is material for a follow-up patch. - omap has a omap_framebuffer_flush function which walks the connector->encoder->crtc links and is called from many contexts. Some look like they don't acquire mode_config.mutex, so this is already racy. Again fixing this is material for a separate patch. - The radeon hot_plug function to retrain DP links looks at connector->dpms. Currently this happens without any locking, so is already racy. I think radeon_hotplug_work_func should gain mutex_lock/unlock calls for the mode_config.connection_mutex. - Same applies to i915's intel_dp_hot_plug. But again, this is already racy. - i915 load_detect code needs to acquire this lock. Which means the w/w dance due to Rob's work will be nicely contained to _just_ this function. I've added fixme comments everywhere where it looks suspicious but in the sysfs code. After a quick irc discussion with Dave Airlie it sounds like the lack of locking in there is due to sysfs cleanup fun at module unload. v1: original (only compile tested) v2: missing mutex_init(), etc (from Rob Clark) v3: i915 needs more care in the conversion: - Protect the edp pp logic with the connection_mutex. - Use connection_mutex in the backlight code due to get_pipe_from_connector. - Use drm_modeset_lock_all in suspend/resume paths. - Update lock checks in the overlay code.

This conversion requires two common code patches to introduce the 'physmem' memblock list. We experimented with ticket spinlocks but in the end decided against them as they perform poorly on virtualized systems. But the spinlock cleanup and some small improvements are included. The uaccess code got another optimization, the get_user/put_user calls are now inline again for kernel compiles targeted at z10 or newer machines. This makes the text segment shorter and the code gets a little bit faster.
