Description Avra Sengupta 2015-07-23 06:02:30 UTC 
+++ This bug was initially created as a clone of Bug #1240184 +++

Description of problem:

from snpaview-server, for statfs fops we allocate memory for loc->path directly, instead of using GF_CALLOC/GF_MALLOC, that causes assertion failure and crash if debug mode is enabled during configurations.

Version-Release number of selected component (if applicable):

mainline

How reproducible:

100%

Steps to Reproduce:
1.enablde debig mode during building using ./configure --enable-debug
2.create volume start it
3.enable uss
4.create an activate snapshot
5.check getconf NAME_MAX /mnt/.snaps

Actual results:

this causes mount process to crash

Expected results:

should not crash mount point
