similar to: [PATCH] btrfs: Fix logical to physical block address mapping

The current btrfs support did not handled multiple stripes stored in chunk items, hence skipping the physical addresses that were needed to do the mapping. Besides, the chunk tree may contain DEV_ITEM keys which store information on all of the underlying block devices, so we must skip them instead of finishing lookup. The bug was reproduced with btrfs-progs v4.2.2. Cc: Gene Cumm <gene.cumm

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

I am working on writing a search method where a user can type a string of words and I return all the objects that have fields that match all of the words in one or a combination of fields. Person first_name last_name Pet name Person has_many :pets I want to write some SQL so that if I search for "Tony AAAA" I will get all the people who have Tony and AAA either in their

Dear list, I need some clues on this. I have two excel files and I basically want to map one to the other one. Can you give me some hints how to do it? The first excel file, named as "Susan_probe.xls", there are two columns, "PROBE_ID1" and "SEARCH_KEY1" PROBE_ID1 SEARCH_KEY1 ILMN_30212 ILMN_30212 ILMN_1285 ILMN_1285 ILMN_137964 ILMN_137964 ILMN_138109

The following case will make the incompat/compat flag of the super block be recovered. Task1 |Task2 flags = btrfs_super_incompat_flags(); | |flags = btrfs_super_incompat_flags(); flags |= new_flag1; | |flags |= new_flag2; btrfs_set_super_incompat_flags(flags); | |btrfs_set_super_incompat_flags(flags); the new_flag1 is recovered. In order to avoid this problem, we

Hello, This patch series adds an initial implementation of restriper (it''s a clever name for relocation framework that allows to do selective profile changing and selective balancing with some goodies like pausing/resuming and reporting progress to the user. Profile changing is global (per-FS) so far, per-subvolume profiles require some discussion and can be implemented in future.

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially. This patch is developed and on top of the send/receive btrfs and btrfs-progs repo at git://github.com/ablock84/linux-btrfs.git (send-v2) git://github.com/ablock84/btrfs-progs.git (send-v2)

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented. To try the new disk format, you need fresh formatted btrfs.

When the binary search returns 0 (exact match), the target key will necessarily be at slot 0 of all nodes below the current one, so in this case the binary search is not needed because it will always return 0, and we waste time doing it, holding node locks for longer than necessary, etc. Below follow histograms with the times spent on the current approach of doing a binary search when the

I made an attempt to partly decrease fragment by using a preallocated area of multiple size of a std blocksize for a tree block when it is COWed. The basic idea is that if any a tree block need to be created, we offer, say, 2 or 4 multiples of a std blocksize for it, then use the first block in the continuous blocks. When this block need a cow in the future, a new free block in these continuous

The attached patch implements a feature that would make my interaction with ssh somewhat more secure. When connecting to a host whose key is not in the known_hosts file, this patch makes ssh tell the user about any other hosts in the known_hosts file that have the same key. For example, if I have host A in my known_hosts file, and try to connect to host B which is an alias for A, ssh will tell

If you look the code carefully, you will see all the tree_mod_alloc() has to use GFP_ATOMIC. However, the original code pass the wrong arg gfp_t in some places, this dosen''t cause any problems, because in the tree_mod_alloc(), it ignores arg gfp_t and just use GFP_ATOMIC directly, this is not good. However, i think we should try best not to allocate with GFP_ATOMIC, so i keep the gfp_t

Remove unused variable in btrfs-image.c (update_super) and update man page documentation about -r option. Running btrfsck on a restored image produces missing chunk information. This is because by default, btrfs-image fixes up chunk tree to use 1 stripe pointing to the primary device. This in turns results in btrfsck making some noise. $ ./mkfs.btrfs /dev/sdb2 -f $ ./btrfs-image /dev/sdb2

In trying to track down a weird tree log problem I wanted to make sure that the free space cache was actually valid, which we currently have no way of doing. So this patch adds a bunch of support for the free space cache code and then a checker to fsck. Basically we go through and if we can actually load the free space cache then we will walk the extent tree and verify that the free space cache
