75e849f3 - bcachefs: update min_heap_callbacks to use default builtin swap

Sun, 20 Oct 2024 04:01:59 +0000

bcachefs: update min_heap_callbacks to use default builtin swapReplace the swp function pointer in the min_heap_callbacks of bcachefswith NULL, allowing direct usage of the default builtin swapimplementation.

a2d23f3d - bcachefs: io clock: run timer fns under clock lock

Sun, 30 Jun 2024 01:02:17 +0000

bcachefs: io clock: run timer fns under clock lockWe don't have a way to flush a timer that's executing the callback, andthis is simple and limited enough in scope that we can just use the lockinstead.Needed for the next patch that adds direct wakeups from the allocator tocopygc, where we're now more frequently calling io_timer_del() on anexpiring timer.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/clock.c

1fcce6b8 - bcachefs: remove heap-related macros and switch to generic min_heap

Fri, 24 May 2024 15:29:58 +0000

bcachefs: remove heap-related macros and switch to generic min_heapDrop the heap-related macros from bcachefs and replacing them with thegeneric min_heap implementation from include/linux. By doing so, codereadability is improved by using functions instead of macros. Moreover,the min_heap implementation in include/linux adopts a bottom-up variationcompared to the textbook version currently used in bcachefs. Thisbottom-up variation allows for approximately 50% reduction in the numberof comparison operations during heap siftdown, without changing the numberof swaps, thus making it more efficient.[visitorckw@gmail.com: fix missing assignment of minimum element] Link: https://lkml.kernel.org/r/20240602174828.1955320-1-visitorckw@gmail.comLink: https://lkml.kernel.org/ioyfizrzq7w7mjrqcadtzsfgpuntowtjdw5pgn4qhvsdp4mqqg@nrlek5vmisbuLink: https://lkml.kernel.org/r/20240524152958.919343-17-visitorckw@gmail.comSigned-off-by: Kuan-Wei Chiu Reviewed-by: Ian Rogers Acked-by: Kent Overstreet Cc: Adrian Hunter Cc: Alexander Shishkin Cc: Arnaldo Carvalho de Melo Cc: Bagas Sanjaya Cc: Brian Foster Cc: Ching-Chun (Jim) Huang Cc: Coly Li Cc: Ingo Molnar Cc: Jiri Olsa Cc: Mark Rutland Cc: Matthew Sakai Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Randy Dunlap Signed-off-by: Andrew Morton List of files: /linux-6.15/fs/bcachefs/clock.c

d92b83f5 - bcachefs: bch2_kthread_io_clock_wait() no longer sleeps until full amount

Mon, 15 Jan 2024 19:15:26 +0000

bcachefs: bch2_kthread_io_clock_wait() no longer sleeps until full amountDrop t he loop in bch2_kthread_io_clock_wait(): this allows the codethat uses it to be woken up for other reasons, and fixes a bug whererebalance wouldn't wake up when a scan was requested.This raises the possibility of spurious wakeups, but callers shouldalways be able to handle that reasonably well.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/clock.c

bcachefs: Heap allocate printbufsThis patch changes printbufs dynamically allocate and reallocate abuffer as needed. Stack usage has become a bit of a problem, and a majorcause of that has been static size string buffers on the stack.The most involved part of this refactoring is that printbufs must now beexited with printbuf_exit().Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/clock.c

2abe5420 - bcachefs: Persist 64 bit io clocks

Thu, 21 Jan 2021 20:28:59 +0000

bcachefs: Persist 64 bit io clocksOriginally, bcachefs - going back to bcache - stored, for each bucket, a16 bit counter corresponding to how long it had been since the bucketwas read from. But, this required periodically rescaling counters onevery bucket to avoid wraparound. That wasn't an issue in bcache, wherewe'd perodically rewrite the per bucket metadata all at once, but inbcachefs we're trying to avoid having to walk every single bucket.This patch switches to persisting 64 bit io clocks, corresponding to the64 bit bucket timestaps introduced in the previous patch withKEY_TYPE_alloc_v2.Signed-off-by: Kent Overstreet Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/clock.c
