Hmm, I dont think that this is terrible. However, since I dont belive that Linux guarantees the stability of its interfaces, I think that adding a trivial test for this would be waranteed.

projects/compiler-rt/lib/builtins/clear_cache.c I suggest two small changes here. 1. Mark it however required to avoid inlining, i.e. for the x86/amd64 case. Control transfer is required. I realize it is likely anyway, you aren't likely to "fall from" the caller into the code. 2. #elif defined(_WIN32) && (defined(__arm__) || defined(__aarch64__)) be changed to just: #elif

So when I added the clear_cache option I screwed up and took the break out of the space_cache case statement, so whenever you mount with space_cache you also get clear_cache, which does you no good if you say set space_cache in fstab so it always gets set. This patch adds the break back in properly. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> --- fs/btrfs/super.c | 1 + 1

Rename no_space_cache option to nospace_cache to be more consistent with the rest, where the simple prefix ''no'' is used to negate an option. The option has been introduced during the -rc1 cycle and there are has not been widely used, so it''s safe.

Hello, I wanted to make sure that my boot slowdown was related to space_cache so I rebooted the PC several times and it did become slower again. What is more, it doesn''t seem like I even need to generate any actual IO traffic to trigger this. I thought I might give clear_cache a shot again and to test the boot speed with nospace_cache as well. After first booting with

Hi all I received the following patch for compiling ctypes module for Python on FreeBSD from Keith White (I'm in no position to judge this fix, I'm just passing it on). Is there anyone on this list being able to commit this code?

I''m trying to figure out how to clear the for a worker from my controller. In my aysnc_xxx process I set cache[key]. However, I don''t see an easy way to clear the cache from a controller with invoking something on the worker. What I was looking for was something like MiddleMan(:worker_name, :worker_key_name).cache[key]= Is there something like that and I''m just

Hi, What is the reason for excluding clear_cache.c from ARM builds of compiler_rt? Where __clear_cache is defined in that case? Thanks, Damjan

Folks, To implement this bug: http://llvm.org/bugs/show_bug.cgi?id=19142 I need an LLVM intrinsic to communicate the need to lower the builtin wither to noop or a call or even a sequence of instructions. I thought about: void @llvm.clear_cache(i8 * begin, i8 * end) to simulate precisely GCC's builtin: void __builtin___clear_cache (char *begin, char *end) which will be, by default,

Dear list members, When I tried to recover my partition from the space cache bug (see http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg24360.html ), I issued the command `mount -o clear_cache -t btrfs /dev/sda7 /aaa/aaa`. After 10 minutes the mount command segfaulted. I cloned the latest btrfs-progs from Josef''s Github account and ran the `btrfsck --repair` twice on the

Dear list members, Yesterday I was about to restart my computer and that''s why I closed every opened applications: three Eclipse instances, two other Java applications, 2 web browsers etc. It involved a lot of IO operations and before everything could settle down my system became unresponsive. I mean X & co. worked fine, but anything related to IO (opening a new screen, a new

I am new to syslinux/extlinux. Can I boot from a linux btrfs subvolume? I am getting "Failed to load ldlinux.c32" when I attempt to boot from a btrfs subvolume. Setup: 1) I have a USB disk with one partition. The partition is marked "active". 2) I make a btrfs filesystem with "mkfs.btrfs /dev/sdd1". I mount the partiton and execute "btrfs su create root".

Hi all, I had been clearing the space cache on my btrfs vol (Debian 3.10.11-1 btrfs-tools 2013-7-5) by changing the fstab to "nospace_cache, clear_cache". I ran btrfsck --repair and it said: "cache and super generation don''t match, space cache will be invalidated." Can one of the dev''s please tell me whether that message means that the space cache

Hi everyone, We seem to have allowed our documented target-independent intrinsics to acquire a somewhat-haphazard naming system, and I think we should standardize on one convention. All of the intrinsics have 'llvm.' as a prefix, and some also have some additional prefix 'llvm.dbg.', 'llvm.eh.', 'llvm.experimental.', etc., but after that we lose consistency. When

We create two subvolumes (meego_root and meego_home) in btrfs root directory. And set meego_root as default mount subvolume. After we remount btrfs, meego_root is mounted to top directory by default. Then when we try to mount meego_home (subvol=meego_home) to a subdirectory, it failed. The problem is when default mount subvolume is set to meego_root, we search meego_home in meego_root but can not

I went through the gallium-nine tree and picked out nouveau patches that are general bug-fixes. The first bunch I'd like to also get into 10.2. I've reviewed all of them and they make sense to me, but sending them out for public review as well in case there are any objections. Unless I hear objections, I'd like to push this by Friday.
