cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget
cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget
Rather than allocating an inode and filling it out, have
cifs_get_inode_info fill out a cifs_fattr and call cifs_iget. This means
a pretty hefty reorganization of cifs_get_inode_info.
For the readdir codepath, add a couple of new functions for filling out
cifs_fattr's from different FindFile response infolevels.
Finally, remove cifs_new_inode since there are no more callers.
