Subject: ovl: select EXPORTFS
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=72d42504bd7faa6de1c1644b5e46652933e040a6;p=linux.git

ovl: select EXPORTFS

We get a link error when EXPORTFS is not enabled:

ERROR: "exportfs_encode_fh" [fs/overlayfs/overlay.ko] undefined!
ERROR: "exportfs_decode_fh" [fs/overlayfs/overlay.ko] undefined!

This adds a Kconfig 'select' statement for overlayfs, the same way that
it is done for the other users of exportfs.

Fixes: 3a1e819b4e80 ("ovl: store file handle of lower inode on copy up")
