* vfs: Allow filesystems to access their private mount dataDaniel Rosenberg2017-04-131-1/+3
| | | | | | | | | | | | | | Now we pass the vfsmount when mounting and remounting. This allows the filesystem to actually set up the mount specific data, although we can't quite do anything with it yet. show_options is expanded to include data that lives with the mount. To avoid changing existing filesystems, these have been added as new vfs functions. Change-Id: If80670bfad9f287abb8ac22457e1b034c9697097 Signed-off-by: Daniel Rosenberg <drosen@google.com>
* get rid of s_files and files_lockAl Viro2016-08-261-3/+0
| | | | | | | | | | | | | | commit eee5cc2702929fd41cce28058dc6d6717f723f87 upstream. The only thing we need it for is alt-sysrq-r (emergency remount r/o) and these days we can do just as well without going through the list of files.
