* vfs_btrfs: advertise per-file compression capabilityDavid Disseldorp2013-11-221-0/+15
| | | | | | | | | | Plumb into the get_fs_capabilities code path to advertise the FILE_FILE_COMPRESSION attribute. Also, document file compression support in the VFS btrfs man page. Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

* vfs_btrfs: add [GET/SET]_COMPRESSION handlersDavid Disseldorp2013-11-221-2/+117
| | | | | | | | | Translate such requests into FS_IOC_GETFLAGS and FS_IOC_SETFLAGS ioctls respectively. The module makes no distinction between compression types, only whether or not compression is enabled. Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* vfs: add [GET/SET]_COMPRESSION hooksDavid Disseldorp2013-11-223-0/+112
| | | | | | | | | | | | | | | The VFS interfaces are sychronous, as the operations only modify meta-data. These hooks are dependent on support for transparent compression by the underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST. Support for other filesystems providing transparent comression, such as Btrfs and ZFS, can be added in future. The get_compression function takes fsp and smb_fname arguments. The smb_fname argument is needed due to the current dosmode() code-path. Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>

| | | | | | | | | | | | Checking if the directory is empty using 'nlink == 2' only checks if there are no subdirectories. It doesn't indicate if there are files in the directory.

* Revert "s3-vfs: Fix stream_depot vfs module on btrfs."David Disseldorp2013-11-121-8/+8
| | | | | | | | | | | | | | | | This reverts commit 29f12e7d5960906935e3af1405e9759a07d64750. The wrong patch was pushed, according to Andreas: I sent a second version cause the first was not complete. I've discussed with Volker after I sent the patch and then sent a new patch which a) also does the right thin in the unlink case b) only tried to remove the server is the deletion of the file was successful.
