btrfs: Fix mismatching struct members in ioctl.h

2012-05-04T19:16:06Z

Fix the size members of btrfs_ioctl_ino_path_args and btrfs_ioctl_logical_ino_args. The user space btrfs-progs utilities used __u64 and the kernel headers used __u32 before. Signed-off-by: Alexander Block Signed-off-by: Chris Mason

Btrfs: allow for canceling restriper

2012-01-16T20:04:49Z

Implement an ioctl for canceling restriper. Currently we wait until relocation of the current block group is finished, in future this can be done by triggering a commit. Balance item is deleted and no memory about the interrupted balance is kept. Signed-off-by: Ilya Dryomov

Btrfs: allow for pausing restriper

2012-01-16T20:04:49Z

Implement an ioctl for pausing restriper. This pauses the relocation, but balance is still considered to be "in progress": balance item is not deleted, other volume operations cannot be started, etc. If paused in the middle of profile changing operation we will continue making allocations with the target profile. Add a hook to close_ctree() to pause restriper and free its data structures on unmount. (It's safe to unmount when restriper is in "paused" state, we will resume with the same parameters on the next mount) Signed-off-by: Ilya Dryomov

Btrfs: add basic restriper infrastructure

2012-01-16T20:04:47Z

Add basic restriper infrastructure: extended balancing ioctl and all related ioctl data structures, add data structure for tracking restriper's state to fs_info, etc. The semantics of the old balancing ioctl are fully preserved. Explicitly disallow any volume operations when balance is in progress. Signed-off-by: Ilya Dryomov

Btrfs: fix the new inspection ioctls for 32 bit compat

2011-11-06T08:08:49Z

The new ioctls to follow backrefs are not clean for 32/64 bit compat. This reworks them for u64s everywhere. They are brand new, so there are no problems with changing the interface now. Signed-off-by: Chris Mason

btrfs: new ioctls to do logical->inode and inode->path resolving

2011-09-29T10:54:28Z

these ioctls make use of the new functions initially added for scrub. they return all inodes belonging to a logical address (BTRFS_IOC_LOGICAL_INO) and all paths belonging to an inode (BTRFS_IOC_INO_PATHS). Signed-off-by: Jan Schmidt

btrfs: added helper functions to iterate backrefs

2011-09-29T10:54:27Z

These helper functions iterate back references and call a function for each backref. There is also a function to resolve an inode to a path in the file system. Signed-off-by: Jan Schmidt

Btrfs: add mount -o auto_defrag

2011-05-26T21:52:15Z

This will detect small random writes into files and queue the up for an auto defrag process. It isn't well suited to database workloads yet, but works for smaller files such as rpm, sqlite or bdb databases. Signed-off-by: Chris Mason

btrfs: add readonly flag

2011-05-12T12:48:31Z

setting the readonly flag prevents writes in case an error is detected Signed-off-by: Arne Jansen
