corresponds to?

btrfs_search_slot+0x8e8/0xb80 maps to fs/btrfs/ctree.c:2751
                write_lock_level = BTRFS_MAX_LEVEL;

That doesn't make sense, presumably btrfs_search_slot+0x8e8/0xb80 should
point at or right after the instruction which called
btrfs_set_path_blocking. So either line 2796, 2894, 2901 or 2918 .

I might be calculating to wrong address, could you please have a look on
the obj dump for files I have sent (which are less than 2MB)

I have sent direct message attaching vmlinux and the obj dump for
ctree.c and locking.c

I just got a message from : InterScan Messaging Security Suite about
some policy being broken and no vmscan.

Sorry, my vmlinux was above 28Mb.
