In autofs this raven> corresponds to a mount failure on a autofs managed mount entry that raven> is browsable (and so the mount point directory exists). raven> While this problem has been present for a long time I've avoided raven> resolving it because it was not very visible. But now that autofs v5 raven> has "mount and expire on demand" of nested multiple mounts, such as raven> is found when mounting an export list from a server, solving the raven> problem cannot be avoided any longer. raven> I've tried very hard to find a way to do this entirely within the raven> autofs4 module but have not been able to find a satisfactory way to raven> achieve it. raven> So, I need to propose a change to the VFS. raven> Signed-off-by: Ian Kent Acked-by: Jeff Moyer -Jeff
