/**
* struct v9fs_dentry - 9p private data stored in dentry d_fsdata
* @fidlist: list of FIDs currently associated with this dentry
*
* This structure defines the 9p private data associated with
* a particular dentry. In particular, this private data is used
* to lookup which 9P FID handle should be used for a particular VFS
* operation. FID handles are associated with dentries instead of
* inodes in order to more closely map functionality to the Plan 9
* expected behavior for FID reclaimation and tracking.
*
* Protected by ->d_lock of dentry it belongs to.
*
* See Also: Mapping FIDs to Linux VFS model in
* Design and Implementation of the Linux 9P File System documentation
