+ * struct export_operations - for nfsd to communicate with file systems
+ * @decode_fh:      decode a file handle fragment and return a &struct dentry
+ * @encode_fh:      encode a file handle fragment from a dentry
+ * @get_name:       find the name for a given inode in a given directory
+ * @get_parent:     find the parent of a given directory
+ * @get_dentry:     find a dentry for the inode given a file handle sub-fragment
+ * @find_exported_dentry:
+ *      set by the exporting module to a standard helper function.
+ *
+ * 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.
+ *
+ *    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.
+ *
+ *    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.
+ *
+ * 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).
+ *
+ * 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_mutex 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_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_mutex down
+ *    get_name is not (which is possibly inconsistent)

- * struct export_operations - for nfsd to communicate with file systems

- * @encode_fh:      encode a file handle fragment from a dentry
- * @get_name:       find the name for a given inode in a given directory
- * @get_parent:     find the parent of a given directory

- * @find_exported_dentry:
- *      set by the exporting module to a standard helper function.
- *
- * 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.
- *
- *    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.
- *
- *    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.
- *
- * 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).
- *
- * 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_mutex 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_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_mutex down
- *    get_name is not (which is possibly inconsistent)

+ *    from starting while a check is in progress.  Some dma engines can perform
+ *    the check without damaging the parity block, in these cases the parity
+ *    block is re-marked up to date (assuming the check was successful) and is
+ *    not re-read from disk.
+ * 2/ When a write operation is requested we immediately lock the affected
+ *    blocks, and mark them as not up to date.  This causes new read requests
+ *    to be held off, as well as parity checks and compute block operations.
+ * 3/ Once a compute block operation has been requested handle_stripe treats
+ *    that block as if it is up to date.  raid5_run_ops guaruntees that any

+ *    the compute block completes.
