2022-06-22Fix bdev_logical_block_size()Kent Overstreet
We were returning sectors instead of bytes. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-06-22Fix printk_ratelimited()Kent Overstreet
printk_ratelimited was behind an #ifdef CONFIG_PRINTK, which we don't define, so it was a complete noop - oops. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-06-18cmd_dump: Use buffered IO for reading device metadataKent Overstreet
We're reading device metadat in mostly sequential order - buffered IO will be faster than O_DIRECT. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>

2022-03-28Heap code fixKent Overstreet
When deleting an entry from a heap that was at entry h->used - 1, we'd end up calling heap_sift() on an entry outside the heap - the entry we just removed - which would end up re-adding it to the heap and deleting something we didn't want to delete. Oops... Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-03-21Shrinker improvementsKent Overstreet
After memory allocation failure, don't rely on /proc/meminfo to figure out how much memory we should free - instead unconditionally free 1/8th of each cache. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2022-03-21Better bio_alloc_bioset()Kent Overstreet
bio_alloc_bioset() now uses mempools, so we don't segfault on memory allocation failure. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>

2021-10-16Fix 32 bit io regressionBrett Holman
In commit ba1dbafc1fce I reverted 9942fc82d43b, which was a workaround for an upstream 32bit libaio bug. Oops. Signed-off-by: Brett Holman <bholman.devel@gmail.com>

2020-05-05Fix building on muslYuxuan Shui
* Add missing linux/stddef.h includes * Explicitly cast PAGE_SIZE to size_t. PAGE_SIZE is defined without UL suffix in musl * Musl doesn't define PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, so initialize the mutexes with pthread_once.
2019-12-14Increase stack size of userspace threads to 32k.Justin Husted
Certain fuse tests crashed inside of libc calls such as fprintf() with only 16k of stack. Signed-off-by: Justin Husted <sigstop@gmail.com>
2019-12-04Put valgrind support behind CONFIG_VALGRINDKent Overstreet
2019-11-07Make userspace blkdev cleanup code more robust.Justin Husted
The existing cleanup code would silently cancel disk IO requests, if somehow the calling code did not wait for completion. This code now tracks requests and will bug if any are lost. Signed-off-by: Justin Husted <sigstop@gmail.com>
2019-11-07Fix refcount bug in blkdev and timer kthreads.Justin Husted
The shutdown code in d79d57e and b20e160 had a race condition during shutdown, due to not owning a reference on the associated task_struct while the associated threads shut themselves down. Patch over this by taking an appropriate reference. Signed-off-by: Justin Husted <sigstop@gmail.com>

2019-11-03Change preempt_disable() etc. to use a recursive mutex.Justin Husted
This is part of the userspace implementation of the kernel APIs for bcachefs-tools. The previous implementation just provided a barrier, but this isn't sufficient to make the associated percpu implementation safe. Signed-off-by: Justin Husted <sigstop@gmail.com>
2019-10-18Add valgrind handling: data read from io_submit was not being markedJustin Husted
properly. Manually mark it. This might be better done by improving the valgrind wrapper for io_submit.
