correct before doing any fop The following operations might lead to problems: * Create a file on the glusterfs mount point * Create a snapshot (say "snap1") * Access the contents of the snapshot * Delete the file from the mount point * Delete the snapshot "snap1" * Create a new snapshot "snap1" Now accessing the new snapshot "snap1" gives problems. Because the inode and dentry created for snap1 would not be deleted upon the deletion of the snapshot (as deletion of snapshot is a gluster cli operation, not a fop). So next time upon creation of a new snap with same name, the previous inode and dentry itself will be used. But the inode context contains old information about the glfs_t instance and the handle in the gfapi world. Directly accessing them without proper check leads to ENOTCONN errors. Thus the glfs_t instance should be checked before accessing. If its wrong, then right instance should be obtained by doing the lookup.
