+Subject: swapon: Document btrfs limitation with swapfiles
+References: bnc#616617
+
+ Btrfs, as of 2.6.35, is unable to allow swapfiles to be used on its
+ filesystems. This is due to the swapfile implementation wanting to build
+ an extent map of each block in the file and expecting it to be static
+ for the life of the swapfile.
+
+ Btrfs can't guarantee this and refuses to return the mapping. The swapfile
+ implementation just makes a comment about there being holes in the file -
+ but that's how btrfs denies the mapping.
+
+ This patch adds a section to the swapon manpage to document it.

++.PP
++.B swapon
++may not work correctly when using a swap file with some versions of btrfs.
++This is due to the swap file implementation in the kernel expecting to be able
++to write to the file directly, without the assistance of the file system.
++Since btrfs is a copy-on-write file system, the file location may not be
++static and corruption can result. Btrfs actively disallows the use of files
++on its file systems by refusing to map the file. This can be seen in the system
++log as "swapon: swapfile has holes." One possible workaround is to map the
++file to a loopback device. This will allow the file system to determine the
++mapping properly but may come with a performance impact.
