Subject: [PATCH 3/8] Btrfs-progs: refactor resolve_root() function a bit
Don't pass a pointer to root_id to resolve_root(). It's always the same as
ri->root_id, passing a pointer hints that root_id can somehow change which is
not true.

Subject: [PATCH 6/8] Btrfs-progs: allow dup for data chunks in mixed mode
Before commit a46e7ff2 was merged it was possible to create dup for
data+metadata chunks (mixed mode) by giving -m raid1 -d raid1 -M to
mkfs. a46e7ff2 purposefully disabled behind the scenes profile
upgrading/downgrading, so give users a chance to pick dup explicitly and
bail if dup for data is requested in normal mode.

Subject: [PATCH] btrfs-progs: mkfs: disallow uneven data/metadata blocksize
for mixed
With support for bigger metadata blocks, we must avoid different
block size for mixed block groups, this causes corruption
(xfstests/083).

+.TH BTRFS-CONVERT 8
+.SH NAME
+btrfs-convert \- convert ext2/ext3/ext4 filesystem image to btrfs in-place
+.SH SYNOPSIS
+.B btrfs-convert \fB[\-dinL]\fP \fB[\-r]\fP \fB[\-l\fP \fILABEL\fP\fB]\fP \fIdevice\fP
+.SH DESCRIPTION
+.B btrfs-convert
+is used to convert a ext2/ext3/ext4 filesystem image to a btrfs one. This is
+performed on an unmounted image. The conversion is done in-place and it's
+possible to do a rollback to original fs. The original filesystem image is
+accessible as a subvolume named \fIext2\_subvol\fP.
+
+The success of the operation depends on amount of free space in the original
+filesystem, as btrfs uses this space to store it's own metadata and just adds
+pointers to the data blocks.
+
+Duration of the operation depends on fragmentation and allocated space on the
+orignal filesystem, it may take seveal hours for a terabyte-sized filesystem.
+
+If the operation does not finish succesfully, the image is recognized as the
+original fileystem.
+
+.SH OPTIONS
+.TP
+\fB\-d\fP
+Disable data checksumming. This may speed up the convert operation.
+.TP
+\fB\-i\fP
+Do not convert ACLs.
+.TP
+\fB\-n\fP
+Disable packing of small files.
+.TP
+\fB\-l\fR \fILABEL\fP
+Set the label of btrfs filesystem to \fILABEL\fP.
+.TP
+\fB\-L\fP
+Copy label from the original filesystem to btrfs.
+.TP
+\fB\-r\fP
+Try rollback to the original filesystem. Beware that this may not always
+succeed if the btrfs filesystem has been changed in a way that prevents this.
+
+.SH CAVEATS
+The resulting filesystem will inherit the fragmentation and it's possible to
+run whole filesystem defragmentation and then balance.
+
+The raid profile of both data and metada will be \fIsingle\fP, this is not the
+same as default mkfs will create. Use balance with convert filter to change
+raid profile you want.
+
+Security labels or quotas are not transferred to the new filesystem.
+
+Block sizes must be at least of btrfs supported size (currently 4KB on x86_64).
+
+.SH AVAILABILITY
+.B btrfs-convert
+is part of btrfs-progs.
+.SH SEE ALSO
+.BR mkfs.btrfs (8)
