search for: btrfs_ioctl_search_key

Hi all, following the thread about the BTRFS_IOC_TREE_SEARCH ioctl [1], I made a patch which try to address the problem of restarting the ioctl. In the current solution is the application during the restart of the search to fill the min_* fields in the "struct btrfs_ioctl_search_key". In general the values set are the last one returned "+1". But doing so we reduce the "acceptance criteria window". I propose to add three more fields in the struct btrfs_ioctl_search_key: + /* starting search key fields */ + __u32 start_type; + __u64...

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)

The kernel patch series just sent (Subject: "Btrfs: scrub: print path to corrupted files and trigger nodatasum fixup") introduces two new ioctls to do in-kernel filesystem path construction. This series provides the corresponding userspace changes, adding two new commands to the btrfs utility: -- btrfs resolve inode [-v] <inode> <path> resolves an <inode> to all

Hello, This is the userspace part of restriper, rebased onto the new progs infrastructure. Restriper commands are located under ''balance'' prefix, which is now the top level command group. However to not confuse existing users ''balance'' prefix is also available under ''filesystem'': btrfs [filesystem] balance start btrfs [filesystem] balance

This is the next patch series for scrub userland tools. Change log v1->v2: - commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem scrub ..." - ability to scrub a single device instead of a whole file system - superfluous command line options removed - resume is now a separate command ("scrub resume") instead of "scrub start -r" -
