[PATCH v2 00/10] fs: NTFS read-write driver GPL implementation by Paragon Software.

[Konstantin Komarov]

This patch adds NTFS Read-Write driver to fs/ntfs3.

Having decades of expertise in commercial file systems development and huge
test coverage, we at Paragon Software GmbH want to make our contribution to
the Open Source Community by providing implementation of NTFS Read-Write
driver for the Linux Kernel.

This is fully functional NTFS Read-Write driver. Current version works with
NTFS(including v3.1) and normal/compressed/sparse files and supports journal replaying.

We plan to support this version after the codebase once merged, and add new
features and fix bugs. For example, full journaling support over JBD will be
added in later updates.

v2:
 - patch splitted to chunks (file-wise)
 - build issues fixed
 - sparse and checkpatch.pl errors fixed
 - NULL pointer dereference on mkfs.ntfs-formatted volume mount fixed 
 - cosmetics + code cleanup

Thanks.
Proper ntfs read/write support will be great addition.

Trivia:

If this patchset is submitted again with a new version,
please use something like "git format-patch --cover-letter"
and "git send-email" so all parts of the patches and replies
have the a single message thread to follow.

That will add an "in-reply-to" header of the 0/m patch
message-id to all n/m parts.

One style oddity I noticed is the use of goto labels in
favor of if block indentation.  It's not terrible style,
just unusual for kernel code.

Hi Joe! Thanks a lot. Will use git send-email for V3. format-patch and --cover-letter have been already used for v2.

AFAIK goto's are being quite widely used in kernel code as well. However V3 will introduce several goto's replacements with if blocks.

Thanks!
