[uml-devel] [PATCH 03/11] uml - hostfs: make hostfs= option work as a jail, as intended.

2007-03-05 Thread Paolo 'Blaisorblade' Giarrusso
From: Paolo 'Blaisorblade' Giarrusso [EMAIL PROTECTED] When a given host directory is specified to be mounted both in hostfs=path1 and with mount option -o path2, we should give access to path1/path2, but this does not happen. Fix that in the simpler way. Also, root_ino can be the empty string
