[PATCH V3 6/8] Cleancache: btrfs hooks for cleancache Filesystems must explicitly enable cleancache by calling cleancache_init_fs anytime a instance of the filesystem is mounted and must save the returned poolid. Btrfs uses its own readpage which must be hooked, but all other cleancache hooks are in the VFS layer includin...

...I/O load on the disks I start seeing these in the domUs: blkfront: barrier: empty write xvdb1 op failed blkfront: xvdb1: barrier or flush: disabled the systems appear to keep working correctly anyway. I discovered the thing in domUs with linux-3.0.3 and got the same with -3.0.4, with or without cleancache enabled, mounting either an ext3 or an ext4 filesystem. The only domU I have running Ubuntu with its kernel 2.6.24-28-xen seems to be immune. Doing something like "dd if=/dev/zero of=/dev/xvdb1" I wasn''t able to trigger those messages even if I tried some different ''bs=...

Hi gang, Here''s some trivial cleanups that I''ve built up while reading through the code. They''ve been run through xfstests -g quick. - z -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

...s user database backend. To synchronize unix password the smbldap-passwd.pl script is used. But I need to sync virtual mail passwords as well. That is why I added to the script few lines of code. Mainly I call external programs. The code is like this: system("/etc/cron.hourly/sqwebmail-cron-cleancache"); When I run smbldap-passwd.pl script from command line it works just fine, however when samba calls it, unix and samba passwords got changed. But my code, which I added, looks like never been called at all. samba 2.2.8a worked fine. I suspect the samba restrict execution of external progra...

XEN_DOM0 is a silent option that has been automatically selected when CONFIG_XEN is selected since 6b0661a5e6fbf. If this option was changed to a menu configurable option then it would only give users the ability to compile out about 100 kbytes of code. As that option makes little sense to choose, and the option isn''t menu selectable anyway, then we can clean up some code by simply

Memory fragmentation introduced by ballooning might reduce significantly the number of 2MB contiguous memory blocks that can be used within a guest, thus imposing performance penalties associated with the reduced number of transparent huge pages that could be used by the guest workload. This patch-set follows the main idea discussed at 2012 LSFMMS session: "Ballooning for transparent huge

Hi, I have noticed that, in the code of linux/drivers/xen/balloon.c, there exists the snippet as this: static int __init balloon_init(void) { unsigned long pfn; struct page *page; if (!xen_pv_domain()) return -ENODEV; ..... } Does it means the driver will not work in HVM? If so, where is the HVN-enabled code for that? 2010-11-16 Rui Chu _______________________________________________
