The FAT file system volume label file stored in the root directory should match the volume label field in the FAT boot sector. As consequence, the max length of these fields ought to be the same. This patch replaces the magic '11' usef in the struct fat_boot_sector with MSDOS_NAME, which is used in struct msdos_dir_entry. Please check the following references: 1. Microsoft FAT specification 2005 (http://read.pudn.com/downloads77/ebook/294884/FAT32%20Spec%20%28SDA%20Contribution%29.pdf). Search for 'volume label'. 2. Microsoft Extensible Firmware Initiative, FAT32 File System Specification (https://staff.washington.edu/dittrich/misc/fatgen103.pdf). Search for 'volume label'. 3. User space code that creates FAT filesystem sometimes uses MSDOS_NAME for the label, sometimes not. Search for 'if (memcmp(label, NO_NAME, MSDOS_NAME))'. I consider to make the same patch there as well. https://github.com/dosfstools/dosfstools/blob/master/src/mkfs.fat.c Link: http://lkml.kernel.org/r/1543096879-82837-1-git-send-email-carmeli.tamir@gmail.comSigned-off-by:

The immutable, append-only and no-dump attributes can only be retrieved with an ioctl; implement the ->getattr() method to return them on statx. Do not return the inode birthtime yet, because the issue of how best to handle the post-2038 timestamps is still under discussion. This patch is needed to pass xfstests generic/424.

Commit 092a5345 ("autofs: take more care to not update last_used on path walk") helped to (partially) resolve a problem where automounts were not expiring due to aggressive accesses from user space. This patch was later reverted because, for very large environments, it meant more mount requests from clients and when there are a lot of clients this caused a fairly significant increase in server load. But there is a need for both types of expire check, depending on use case, so add a mount option to allow for strict update of last use of autofs dentrys (which just means not updating the last use on path walk access).

The parse_options() function uses a long list of parameters, most of which are present in the super block info structure already. The mount parameters set in parse_options() options don't require cleanup so using the super block info struct directly is simpler.

Al Viro made some suggestions to improve the implementation of commit 0633da48 ("fix autofs_sbi() does not check super block type"). The check is unnecessary in all cases except for ioctl usage so placing the check in the super block accessor function adds a small overhead to the common case where it isn't needed. So it's sufficient to do this in the ioctl code only. Also the check in the ioctl code is needlessly complex.

There is no reason why we rearm the waitiqueue upon every fetch_events retry (for when events are found yet send_events() fails).

Upon timeout, we can just exit out of the loop, without the cost of the changing the task's state with an smp_store_mb call.

This patch aims at reducing ep wq.lock hold times in epoll_wait(2). For the blocking case, there is no need to constantly take and drop the spinlock, which is only needed to manipulate the waitqueue. The call to ep_events_available() is now lockless, and only exposed to benign races. Here, if false positive (returns available events and does not see another thread deleting an epi from the list) we call into send_events and then the list's state is correctly seen. Otoh, if a false negative and we don't see a list_add_tail(), for example, from irq callback, then it is rechecked again before blocking, which will see the correct state. In order for more accuracy to see concurrent list_del_init(), use the list_empty_careful() variant -- of course, this won't be safe against insertions from wakeup. For the overflow list we obviously need to prevent load/store tearing as we don't want to see partial values while the ready list is disabled.

The ep->ovflist is a secondary ready-list to temporarily store events that might occur when doing sproc without holding the ep->wq.lock. This accounts for every time we check for ready events and also send events back to userspace; both callbacks, particularly the latter because of copy_to_user, can account for a non-trivial time. As such, the unlikely() check to see if the pointer is being used, seems both misleading and sub-optimal. In fact, we go to an awful lot of trouble to sync both lists, and populating the ovflist is far from an uncommon scenario. For example, profiling a concurrent epoll_wait(2) benchmark, with CONFIG_PROFILE_ANNOTATED_BRANCHES shows that for a two threads a 33% incorrect rate was seen; and when incrementally increasing the number of epoll instances (which is used, for example for multiple queuing load balancing models), up to a 90% incorrect rate was seen. Similarly, by deleting the prediction, 3% throughput boost was seen across incremental threads. Link: http://lkml.kernel.org/r/20181108051006.18751-4-dave@stgolabs.netSigned-off-by:

The current logic is a bit convoluted. Lets simplify this with a standard list_for_each_entry_safe() loop instead and just break out after maxevents is reached.

Patch series "epoll: some miscellaneous optimizations". The following are some incremental optimizations on some of the epoll core. Each patch has the details, but together, the series is seen to shave off measurable cycles on a number of systems and workloads. For example, on a 40-core IB, a pipetest as well as parallel epoll_wait() benchmark show around a 20-30% increase in raw operations per second when the box is fully occupied (incremental thread counts), and up to 15% performance improvement with lower counts. Passes ltp epoll related testcases. This patch(of 6): All callers pass the EP_MAX_NESTS constant already, so lets simplify this a tad and get rid of the redundant parameter for nested eventpolls.

gen_pool_alloc_algo() uses different allocation functions implementing different allocation algorithms. With gen_pool_first_fit_align() allocation function, the returned address should be aligned on the requested boundary. If chunk start address isn't aligned on the requested boundary, the returned address isn't aligned too. The only way to get properly aligned address is to initialize the pool with chunks aligned on the requested boundary. If want to have an ability to allocate buffers aligned on different boundaries (for example, 4K, 1MB, ...), the chunk start address should be aligned on the max possible alignment. This happens because gen_pool_first_fit_align() looks for properly aligned memory block without taking into account the chunk start address alignment. To fix this, we provide chunk start address to gen_pool_first_fit_align() and change its implementation such that it starts looking for properly aligned block with appropriate offset (exactly as is done in CMA).

check_hung_uninterruptible_tasks() is currently calling rcu_lock_break() for every 1024 threads. But check_hung_task() is very slow if printk() was called, and is very fast otherwise. If many threads within some 1024 threads called printk(), the RCU grace period might be extended enough to trigger RCU stall warnings. Therefore, calling rcu_lock_break() for every some fixed jiffies will be safer. Link: http://lkml.kernel.org/r/1544800658-11423-1-git-send-email-penguin-kernel@I-love.SAKURA.ne.jpSigned-off-by:

Based on commit 401c636a ("kernel/hung_task.c: show all hung tasks before panic"), we could get the call stack of hung task. However, if the console loglevel is not high, we still can not see the useful panic information in practice, and in most cases users don't set console loglevel to high level. This patch is to force console verbose before system panic, so that the real useful information can be seen in the console, instead of being like the following, which doesn't have hung task information.

The introduction of these dummy BUILD_BUG_ON stubs dates back to commmit 903c0c7c ("sparse: define dummy BUILD_BUG_ON definition for sparse"). At that time, BUILD_BUG_ON() was implemented with the negative array trick *and* the link-time trick, like this: extern int __build_bug_on_failed; #define BUILD_BUG_ON(condition) \ do { \ ((void)sizeof(char[1 - 2*!!(condition)])); \ if (condition) __build_bug_on_failed = 1; \ } while(0) Sparse is more strict about the negative array trick than GCC because Sparse requires the array length to be really constant. Here is the simple test code for the macro above: static const int x = 0; BUILD_BUG_ON(x); GCC is absolutely fine with it (-Wvla was enabled only very recently), but Sparse warns like this: error: bad constant expression error: cannot size expression (If you are using a newer version of Sparse, you will see a different warning message, "warning: Variable length array is used".) Anyway, Sparse was producing many false positives, and noisier than it should be at that time. With the previous commit, the leftover negative array trick is gone. Sparse is fine with the current BUILD_BUG_ON(), which is implemented by using the 'error' attribute. I am keeping the stub for BUILD_BUG_ON_ZERO(). Otherwise, Sparse would complain about the following code, which GCC is fine with: static const int x = 0; int y = BUILD_BUG_ON_ZERO(x); Link: http://lkml.kernel.org/r/1542856462-18836-3-git-send-email-yamada.masahiro@socionext.comSigned-off-by:
