This patch contains fixes for persistent grants implementation v2: * handle == 0 is a valid handle, so initialize grants in blkback setting the handle to BLKBACK_INVALID_HANDLE instead of 0. Reported by Konrad Rzeszutek Wilk. * new_map is a boolean, use "true" or "false" instead of 1 and 0. Reported by Konrad Rzeszutek Wilk. * blkfront announces the

Hi At line 1118 of src//lib-index/mail-index-map.c, inside the function mail_index_map_move_to_memory, there is: mail_index_map_copy_header(map, map); Valgrind is stating that "Source and destination overlap in memcpy". I'm wondering if this code is just coping the same memory over itself, or if it is doing something useful. Regards, Diego Liziero. --- 1104 void

This patch series proposes two new filters. * truncate: This can truncate, extend, round up or round down the size of a plugin/device. A typical usage is to fix the qemu problem that it can only handle devices which are a multiple of 512-bytes: nbdkit --filter=truncate random size=500 round-up=512 This will serve a virtual device with size 512 bytes. Reading from the last 12 bytes will

..., so I'll add it there. At the moment it's possible to express this in the map file, but only by positively listing the regions you want to be mapped, not by negatively listing regions you want unmapped. > >+static int > >+insert_mapping (struct map *map, const struct mapping *new_mapping) > >+{ > >+ size_t i; > >+ > >+ /* Adjust existing mappings if they overlap with this mapping. */ > >+ for (i = 0; i < map->nr_map; ++i) { > >+ if (mappings_overlap (&map->map[i], new_mapping)) { > >+ /* The four cases are: > >...

This patch implements persistent grants for the xen-blk{front,back} mechanism. The effect of this change is to reduce the number of unmap operations performed, since they cause a (costly) TLB shootdown. This allows the I/O performance to scale better when a large number of VMs are performing I/O. Previously, the blkfront driver was supplied a bvec[] from the request queue. This was granted to

Just installed the latest (Dec. 12) CVS version and one user keeps getting this assertion failure. Todd dovecot: Dec 13 15:53:01 Error: 29718 imap(username): mbox sync: UID inserted in the middle of mailbox /mailhome/new/o/h/username/mbox (4863 > 3417, seq=780, idx_msgs=1913) dovecot: Dec 13 15:53:06 Error: 29718 imap(username): file mail-index-transaction.c: line 129

We are just trying to bring up a new server and chose to use Dovecot rather than the uw-imap from our previous servers. At this point I am just testing with some throw away accounts using squirrelmail. I can load my inbox, but then the imap connection is lost. I presume you need some real information to get your teeth into, so this is going to get a little long. I'll give you three things
