Dave Kleikamp 36b12fb709 JFS: Fix conflicting superblock flags
JFS_NOINTEGRITY and JFS_USRQUOTA are defined to be the same value.
Change JFS_NOINTEGRITY to 0x40 and re-order the flags in the header
file to avoid repeating this problem.

Jan Engelhardt 03a67a46af Fix typos in doc and comments
Changes persistant -> persistent. www.dictionary.com does not know
persistant (with an A), but should it be one of those things you can
spell in more than one correct way, let me know.

Mark Bellon 8fc2751beb [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mounts
If /etc/mtab is a regular file all of the mount options (of a file system)
are written to /etc/mtab by the mount command.  The quota tools look there
for the quota strings for their operation.  If, however, /etc/mtab is a
symlink to /proc/mounts (a "good thing" in some environments) the tools
don't write anything - they assume the kernel will take care of things.

While the quota options are sent down to the kernel via the mount system
call and the file system codes handle them properly unfortunately there is
no code to echo the quota strings into /proc/mounts and the quota tools
fail in the symlink case.

The attached patchs modify the EXT[2|3] and JFS codes to add the necessary
hooks.  The show_options function of each file system in these patches
currently deal with only those things that seemed related to quotas;
especially in the EXT3 case more can be done (later?).

Jan Kara also noted the difficulty in moving these changes above the FS
codes responding similarly to myself to Andrew's comment about possible
VFS migration. Issue summary:

 - FS codes have to process the entire string of options anyway.

 - Only FS codes that use quotas must have a show_options function (for
   quotas to work properly) however quotas are only used in a small number
   of FS.

 - Since most of the quota using FS support other options these FS codes
   should have the a show_options function to show those options - and the
   quota echoing becomes virtually negligible.

Based on feedback I have modified my patches from the original:

   JFS a missing patch has been restored to the posting
   EXT[2|3] and JFS always use the show_options function
       - Each FS has at least one FS specific option displayed
       - QUOTA output is under a CONFIG_QUOTA ifdef
       - a follow-on patch will add a multitude of options for each FS
   EXT[2|3] and JFS "quota" is treated as "usrquota"
   EXT3 journalled data check for journalled quota removed
   EXT[2|3] mount when quota specified but not compiled in

 - no changes from my original patch.  I tested the patch and the codes
   warn but

 - still mount.  With all due respection I believe the comments
   otherwise were a

 - misread of the patch.  Please reread/test and comment.  XFS patch
   removed - the XFS team already made the necessary changes EXT3 mixing
   old and new quotas are handled differently (not purely exclusive)

 - if old and new quotas for the same type are used together the old
   type is silently depricated for compatability (e.g.  usrquota and
   usrjquota)

 - mixing of old and new quotas is an error (e.g.  usrjquota and
   grpquota)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
