With this change, only mountpoints will -count against the limit. - -Reviewed-on: http://gerrit.openafs.org/11945 -Reviewed-by: Benjamin Kaduk <kaduk@mit.edu> -Reviewed-by: Daria Brashear <shadow@your-file-system.com> -Tested-by: BuildBot <buildbot@rampaginggeek.com> -(cherry picked from commit 05f64de7d723a8d5430d9b5928c2025838a6fa52) - -Change-Id: I16e855c8322174604288b7d440b342951dd3a015 ---- - src/afs/LINUX/osi_vnodeops.c | 4 +++- - 1 file changed, 3 insertions(+), 1 deletion(-) - -diff --git a/src/afs/LINUX/osi_vnodeops.c b/src/afs/LINUX/osi_vnodeops.c -index 3c0cb33..ae0513c 100644 ---- a/src/afs/LINUX/osi_vnodeops.c -+++ b/src/afs/LINUX/osi_vnodeops.c -@@ -1555,7 +1555,9 @@ afs_linux_lookup(struct inode *dip, struct dentry *dp) - d_prune_aliases(ip); - - #ifdef STRUCT_DENTRY_OPERATIONS_HAS_D_AUTOMOUNT -- ip->i_flags |= S_AUTOMOUNT; -+ /* Only needed if this is a volume root */ -+ if (vcp->mvstat == 2) -+ ip->i_flags |= S_AUTOMOUNT; - #endif - } - /* --- -2.5.1 - |
