  *
  * Description:
  *    The export_operations structure provides a means for nfsd to communicate
  *    with a particular exported file system  - particularly enabling nfsd and
  *    the filesystem to co-operate when dealing with file handles.
  *
- *    export_operations contains two basic operation for dealing with file handles,
- *    decode_fh() and encode_fh(), and allows for some other operations to be defined
- *    which standard helper routines use to get specific information from the
- *    filesystem.
+ *    export_operations contains two basic operation for dealing with file
+ *    handles, decode_fh() and encode_fh(), and allows for some other
+ *    operations to be defined which standard helper routines use to get
+ *    specific information from the filesystem.
  *
  *    nfsd encodes information use to determine which filesystem a filehandle
- *    applies to in the initial part of the file handle.  The remainder, termed a
- *    file handle fragment, is controlled completely by the filesystem.
- *    The standard helper routines assume that this fragment will contain one or two
- *    sub-fragments, one which identifies the file, and one which may be used to
- *    identify the (a) directory containing the file.

+ *    standard helper routines assume that this fragment will contain one or
+ *    two sub-fragments, one which identifies the file, and one which may be
+ *    used to identify the (a) directory containing the file.
  *
  *    In some situations, nfsd needs to get a dentry which is connected into a
- *    specific part of the file tree.  To allow for this, it passes the function
- *    acceptable() together with a @context which can be used to see if the dentry
- *    is acceptable.  As there can be multiple dentrys for a given file, the filesystem
- *    should check each one for acceptability before looking for the next.  As soon
- *    as an acceptable one is found, it should be returned.

+ *    given file, the filesystem should check each one for acceptability before
+ *    looking for the next.  As soon as an acceptable one is found, it should
+ *    be returned.
  *
  * decode_fh:
- *    @decode_fh is given a &struct super_block (@sb), a file handle fragment (@fh, @fh_len)
- *    and an acceptability testing function (@acceptable, @context).  It should return
- *    a &struct dentry which refers to the same file that the file handle fragment refers
- *    to,  and which passes the acceptability test.  If it cannot, it should return
- *    a %NULL pointer if the file was found but no acceptable &dentries were available, or
- *    a %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or %ENOMEM).
+ *    @decode_fh is given a &struct super_block (@sb), a file handle fragment
+ *    (@fh, @fh_len) and an acceptability testing function (@acceptable,
+ *    @context).  It should return a &struct dentry which refers to the same
+ *    file that the file handle fragment refers to,  and which passes the
+ *    acceptability test.  If it cannot, it should return a %NULL pointer if
+ *    the file was found but no acceptable &dentries were available, or a
+ *    %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or
+ *    %ENOMEM).
  *
  * encode_fh:
- *    @encode_fh should store in the file handle fragment @fh (using at most @max_len bytes)
- *    information that can be used by @decode_fh to recover the file refered to by the
- *    &struct dentry @de.  If the @connectable flag is set, the encode_fh() should store
- *    sufficient information so that a good attempt can be made to find not only
- *    the file but also it's place in the filesystem.   This typically means storing
- *    a reference to de->d_parent in the filehandle fragment.
- *    encode_fh() should return the number of bytes stored or a negative error code
- *    such as %-ENOSPC

  *
  * get_name:
- *    @get_name should find a name for the given @child in the given @parent directory.
- *    The name should be stored in the @name (with the understanding that it is already
- *    pointing to a a %NAME_MAX+1 sized buffer.   get_name() should return %0 on success,
- *    a negative error code or error.
- *    @get_name will be called without @parent->i_sem held.

+ *    buffer.   get_name() should return %0 on success, a negative error code
+ *    or error.  @get_name will be called without @parent->i_sem held.
  *
  * get_parent:
- *    @get_parent should find the parent directory for the given @child which is also
- *    a directory.  In the event that it cannot be found, or storage space cannot be
- *    allocated, a %ERR_PTR should be returned.
+ *    @get_parent should find the parent directory for the given @child which
+ *    is also a directory.  In the event that it cannot be found, or storage
+ *    space cannot be allocated, a %ERR_PTR should be returned.
  *
  * get_dentry:
- *    Given a &super_block (@sb) and a pointer to a file-system specific inode identifier,
- *    possibly an inode number, (@inump) get_dentry() should find the identified inode and
- *    return a dentry for that inode.
- *    Any suitable dentry can be returned including, if necessary, a new dentry created
- *    with d_alloc_root.  The caller can then find any other extant dentrys by following the
- *    d_alias links.  If a new dentry was created using d_alloc_root, DCACHE_NFSD_DISCONNECTED
- *    should be set, and the dentry should be d_rehash()ed.

  *
- *    If the inode cannot be found, either a %NULL pointer or an %ERR_PTR code can be returned.
- *    The @inump will be whatever was passed to nfsd_find_fh_dentry() in either the
- *    @obj or @parent parameters.

  *
  * Locking rules:
- *  get_parent is called with child->d_inode->i_sem down
- *  get_name is not (which is possibly inconsistent)
+ *    get_parent is called with child->d_inode->i_sem down
+ *    get_name is not (which is possibly inconsistent)
