* btrfs-progs: allow device deletion using 'missing' keyword againAlexander Fougner2015-11-16
| | | | | | | | | | Device deletion procedures ensures the device is a block device. This patch introduces 'missing' as keyword again, correctly passing it on to the kernel instead of complaining about 'missing' not being a block device.

* btrfs-progs: mkfs: do not truncate the image when --rootdir is setDavid Sterba2015-11-05
| | | | | | | | | | | | | | With the rootdir option we try to guess the final size of the image and fill it with zeros, preceded by truncation. After patch "Btrfs-progs: Do not force mixed block group creation unless '-M' option is specified" the misc test 002 will fail, because of the non-mixed mode. I think we should not touch the image size (no change for block devices) and try to fit into whatever is provided by user. Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: Allow btrfs_leaf_free_space to accept NULL rootQu Wenruo2015-11-05
| | | | | | | | | | | | | | | Btrfs_leaf_free_space() function is used to determine the leaf/node size. It's OK to use root->nodesize to determine nodesize, but in fact, extent_buffer->len can also be used to determine the nodesize if caller can ensure it's a tree block. So this patch will add support for NULL root for btrfs_leaf_free_space() function, to allow btrfs_print_leaf() functions to be called in gdb or to debug temporary btrfs in make_btrfs() without a valid root.

* btrfs-progs: mkfs: Round device size down to sectorsizeZhao Lei2015-11-03
| | | | | | | | | | | | | | | | | | | | | | | | When do following command in a vm, whose disks are created by qemu-img create -f raw 11 2.6G: # mkfs.btrfs -f /dev/vdd /dev/vde /dev/vdf # btrfs-show-super /dev/vdd /dev/vde /dev/vdf | grep dev_item.total_bytes dev_item.total_bytes 2791727104 dev_item.total_bytes 2791729152 dev_item.total_bytes 2791729152 We can see that the first device's size is little smaller. And it fails xfstests btrfs/011. Reason: First device's size is rounded down to sectorsize in make_btrfs(), but other devices are not. Fix: Round down remain devices' size in btrfs_add_to_fsid().

* btrfs-progs: Rename variables in btrfs_add_to_fsidZhao Lei2015-11-03
| | | | | | | | | | | | | | | | | There are two total_bytes in btrfs_add_to_fsid(), local variable of total_bytes means fs_total_bytes, and device->total_bytes means device's total_bytes. And device's total_bytes in argument is named block_count in current code. This patch rename: total_bytes -> fs_total_bytes block_count -> device_total_bytes To make code more readable.

* btrfs-progs: mkfs: output device list in sorted orderZhao Lei2015-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | list_for_each_entry_reverse() in current code can not output devices in sorted order, because the sequence are broken in btrfs_alloc_chunk(). We can use list_sort() instead. Before patch: # mkfs.btrfs -f /dev/vdd /dev/vde /dev/vdf ... Number of devices: 3 Devices: ID SIZE PATH 3 2.60GiB /dev/vdf 1 2.60GiB /dev/vdd 2 2.60GiB /dev/vde After patch: # mkfs.btrfs -f /dev/vdd /dev/vde /dev/vdf ...
