http://dovecot.org/tools/nfstest.c I wrote a test utility that tests different ways to flush NFS attribute cache and data cache. Please test in your NFS setup and show me the results, so I can make Dovecot v1.1 works well with NFS. Run the test several times (3 should be enough) to make sure the output stays the same, because the attribute cache flushes might incorrectly say "OK&quot...

Hello, I have some trouble with the current setup (it's a testing environment): 2 server with Dovecot 1.1.4 from source (OS Debian testing 2.6.26) (name: "exim" and "exim2") 1 NFS server (OS Debian testing 2.6.26) I use NFS v.4, indexes shared over NFS. The relavant part of Dovecot configuration: dotlock_use_excl = yes mail_nfs_storage = yes mail_nfs_index = yes

This patch has the core work flush function take a worker. When we support multiple workers we can then flush each worker during device removal, stoppage, etc. Signed-off-by: Mike Christie <michael.christie at oracle.com> --- drivers/vhost/vhost.c | 24 +++++++++++++++--------- 1 file changed, 15 insertions(+), 9 deletions(-...

Future AMD SVM supports a new feature called flush by ASID. The idea is to allow CPU to flush TLBs associated with the ASID assigned to guest VM. So hypervisor doesn''t have to reassign a new ASID in order to flush guest''s VCPU. Please review it. Thanks, Wei Signed-off-by: Wei Huang <wei.huang2@amd.com> Signed-off-by: We...

Hi, Is it possible to perform a search without flushing the index? I've got an application that updates the index every 4 hours but I need to be able to search the new data fairly quickly after the index is updated. The problem revolves around the fact that the update is often much less than 10 000 documents so it isn't being flushed until qu...

Hi, I am using the Xapian-0.8.0 snapshot from 15-Apr-2004 02:14, and I am using the same Xapian::WritableDatabase instance for indexing and searching. Currently each search causes a database flush, which is slow. How can I avoid this flush? It seems that I have to modify Xapian to either - search only the already flushed data (eventually missing some hits) or - search the un-flushed data, too. -- Robert Pollak GPG Key ID: 748646AD

Inside this directory this mysql-flush script: https://github.com/qemu/qemu/blob/master/scripts/qemu-guest-agent/fsfreeze-hook.d/mysql-flush.sh.sample I had to adjust this script a little for mariadb 10.0.14.

Hi, on IA64 flushing the whole TLB is very expensive: this is a cpu tlb flush and clearing 16MB of memory (virtual tlb). However, flushing an address range is rather cheap. Flushing an address range on every processors is also cheap (no IPI). Unfortunatly Xen common code flushes the whole TLB after unmapping gra...

On map: only flush when old PTE was valid or invalid PTE may be cached. On unmap: always flush old entry, but skip flush for unaffected IOMMUs.

Ok, one more issue. I've removed the no-op resync() method and now getting rid of numerous raw_ostream::flush() calls. These were required before but now will never do anything but will waste runtime discovering that. To find raw_svector_ostream::flush() calls speficially I locally shadowed raw_ostream:flush() with a deleted flush(): class raw_svector_ostream { ... public: ... void flush() = delete; };...

We want some testsuite coverage of handling non-1 .can_flush values.
