When btrfs_start_transaction() fails, we should call btrfs_std_error() properly for filesystem to readonly. (in this patch, forced readonly framework is used) Signed-off-by: Tsutomu Itoh <t-itoh@jp.fujitsu.com> --- fs/btrfs/file.c | 1 + fs/btrfs/inode.c | 34 +++++++++++++++++++++++++++-------...

This patch finally gives us full proper -ENOSPC handling for btrfs. Now whenever you do a btrfs_start_transaction, you must specify the number of items you are planning to add/delete/modify. The worst case number of blocks that could be modified by changing that number of items will be calculated and checked against the amount of free space in the space_info where the root you are modifying would alloca...

Now that we properly clean up 'trans' in the reader thread, we must not dereference 'trans' from the write thread at any point after trans has been added to the list unless we have grabbed it back off the list ourselves, or we risk an occasional use-after-free or even double free that valgrind can detect.

I'm not observing any noticeable performance differences, but I'm liking the diffstat. I can't push this patch until we release a new libnbd version with the _notify API addition, but am posting it now for playing with things.

We no longer have to track a linked list of in-flight transactions that are pending resolution, but rely instead on libnbd 0.1.6+ doing it on our behalf. Normally, we will get to call nbdplug_register() prior to the notify callback being reached, but under a heavily-loaded system, it is conceivable that the libnbd state machine can manage to fire off our re...

Hello, I am trying to read in elements out of a very large binary file ... the total file is 4 gigs. I want to select rows out of the file, and the current procedure I run works but is prohibitively slow (takes more than a day to run and still won't complete). Is there any faster way to accomplish this? My current procedure looks like this: readHH <- function(file_name,

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.

...l us that it is still in the b+ tree. - When we want to search fs/file trees or the relative log trees, we will try to search the cached extent buffer at first, if we can not find the item, we will do the common search. At some condition, we will jump to the common search directly: I. a new transaction starts. II. the cached extent buffer was cowed. III. the cached extent buffer''s level is below the level we must lock. and so on. And beside that, if we can not find the item, and the slot points to the first the item or the last item in the leaf, we must jump out the cache...

With this, I am finally able to get the nbd plugin to do out-of-order responses to the client. Once this series goes in, we should be ready for Rich to cut a release.
