Raghavendra,
    I looked at the issue, and cat on a file is leading to lookup on it's hardlink,

#Delete file and all links from backend
TEST rm -rf $(find $B0/${V0}5 -inum $(stat -c %i $B0/${V0}5/FILE1))

#Access files
TEST cat $M0/FILE1 <<---- this 
EXPECT_WITHIN $HEAL_TIMEOUT "$SIZE" path_size $B0/${V0}5/FILE1
TEST cat $M0/HL_FILE1
EXPECT_WITHIN $HEAL_TIMEOUT "$SIZE" path_size $B0/${V0}5/HL_FILE1

<raghug> pranithk, checking
<raghug> pranithk, who sent this lookup?
<raghug> on /HL_FILE1
<pranithk> raghug: cat $M0/FILE1, that command sent lookup on this file
<pranithk> raghug: which is confusing
<raghug> pranithk, I doubt it
<raghug> is it possible to prove it?
<raghug> may be by dumping fuse traffic
<raghug> or is it something gone wrong in glusterfs stack
<pranithk> raghug: Is the procedure documented somewhere? How to get that done?
<raghug> for eg., inode_path might've given that link
<raghug> though application was accessing from other link
<pranithk> raghug: ah! I remember seeing such code in EC let me also see..
<pranithk> raghug: either way can you give any link which documents how to get fuse traffic?
<raghug> pranithk, just do a git grep on "inode_parent" and inode_path
<raghug> for the entire codebase
<raghug> pranithk, let me search that
<pranithk> raghug: no no, I want to first check what came in fuse traffic
<pranithk> raghug: I want to learn that part...
<raghug> I am searching for documentation on that :)
