* mmotm 2020-04-17-20-35 uploaded @ 2020-04-18 3:36 akpm [not found] ` <319997c2-5fc8-f889-2ea3-d913308a7c1f@infradead.org> 0 siblings, 1 reply; 3+ messages in thread From: akpm @ 2020-04-18 3:36 UTC (permalink / raw) To: broonie, linux-fsdevel, linux-kernel, linux-mm, linux-next, mhocko, mm-commits, sfr The mm-of-the-moment snapshot 2020-04-17-20-35 has been uploaded to http://www.ozlabs.org/~akpm/mmotm/ mmotm-readme.txt says README for mm-of-the-moment: http://www.ozlabs.org/~akpm/mmotm/ This is a snapshot of my -mm patch queue. Uploaded at random hopefully more than once a week. You will need quilt to apply these patches to the latest Linus release (5.x or 5.x-rcY). The series file is in broken-out.tar.gz and is duplicated in http://ozlabs.org/~akpm/mmotm/series The file broken-out.tar.gz contains two datestamp files: .DATE and .DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss, followed by the base kernel version against which this patch series is to be applied. This tree is partially included in linux-next. To see which patches are included in linux-next, consult the `series' file. Only the patches within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in linux-next. A full copy of the full kernel tree with the linux-next and mmotm patches already applied is available through git within an hour of the mmotm release. Individual mmotm releases are tagged. The master branch always points to the latest release, so it's constantly rebasing. https://github.com/hnaz/linux-mm The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second) contains daily snapshots of the -mm tree. It is updated more frequently than mmotm, and is untested. A git copy of this tree is also available at https://github.com/hnaz/linux-mm This mmotm tree contains the following patches against 5.7-rc1: (patches marked "*" will be included in linux-next)

Seems that file was missed. Also, this code jumps through horrifying hoops in order to initialize locals at their definition site. But the code looks so much better if we Just Don't Do That!

I think the code would look even better if things just Had The Right Type! struct squashfs_sb_info { ... - struct squashfs_stream *stream; + union { + struct squashfs_stream *stream; + struct squashfs_stream __percpu *percpu_stream; + }; int squashfs_decompress(struct squashfs_sb_info *msblk, struct bio *bio, int offset, int length, struct squashfs_page_actor *output) { struct squashfs_stream *stream = get_cpu_ptr(msblk->percpu_stream); int res = msblk->decompressor->decompress(msblk, stream->stream, bh, b, offset, length, output); ... As an aside, that calling convention could do with putting some of the arguments into a struct so the CPU spends less time shuffling arguments from one register to another. ^ permalink raw reply [flat|nested] 3+ messages in thread
