Subject: first access fails with ENOENT after autofs started
Date: Tue, 29 Jan 2008 17:36:08 +0800	[thread overview]
Message-ID: <479EF388.5080805@oracle.com> (raw)

Hi experts,

In RHEL kernel 2.6.18-53 and mainline kernel 2.6.24,
in function autofs4_lookup() in fs/autofs4/root.c,
if dentry is not found in function autofs4_lookup_unhashed(),
a d_instantiate() is done on the dentry passed as parameter instead of 
d_add().

seems this cause a problem that the first access just after autofs 
started to
/path/to/<autofsMountPoint>/<nfsMountPoint> fail with the error ENOENT.

If I rolled back to use d_add(), there is no such problem.
Is this a bug or I omitted something?

thanks,
wengang.
