I found that the length of a file name when created cannot exceed 255
characters, yet, pathconf(), via statfs(), returns the maximum as 260.Signed-off-by: Kevin Dankwardt

This adds three helpers:
fat_make_attrs() - makes FAT attributes from inode.
fat_make_mode() - makes mode_t from FAT attributes.
fat_save_attrs() - saves FAT attributes to inode.Then this replaces: MSDOS_MKMODE() by fat_make_mode(), fat_attr() by
fat_make_attrs(), ->i_attrs = attr & ATTR_UNUSED by fat_save_attrs().
And for root inode, those is used with ATTR_DIR instead of bogus
ATTR_NONE.Signed-off-by: OGAWA Hirofumi

Provide a new mount option ("tz=UTC") for DOS (vfat/msdos) filesystems,
allowing timestamps to be in coordinated universal time (UTC) rather than
local time in applications where doing this is advantageous.In particular, portable devices that use fat/vfat (such as digital
cameras) can benefit from using UTC in their internal clocks, thus
avoiding daylight saving time errors and general time ambiguity issues.
The user of the device does not have to worry about changing the time when
moving from place or when daylight saving changes.The new mount option, when set, disables the counter-adjustment that Linux
currently makes to FAT timestamp info in anticipation of the normal
userspace time zone correction. When used in this new mode, all daylight
saving time and time zone handling is done in userspace as is normal for
many other filesystems (like ext3). The default mode, which remains
unchanged, is still appropriate when mounting volumes written in Windows
(because of its use of local time).I originally based this patch on one submitted last year by Paul Collins,
but I updated it to work with current source and changed variable/option
naming. Ogawa Hirofumi (who maintains these filesystems) and I discussed
this patch at length on lkml, and he suggested using the option name in
the attached version of the patch. Barry Bouwsma pointed out a good
addition to the patch as well.Signed-off-by: Joe Peterson

"struct dirent" is a kernel type here, but is a **different type** in
userspace! This means both the structure and the IOCTL number is wrong!So, this adds new "struct __fat_dirent" to generate correct IOCTL number.
And kernel stuff moves to under __KERNEL__.Signed-off-by: OGAWA Hirofumi

Currently, free_clusters is not updated until it is trusted, because
Windows doesn't update it correctly.But if user is using FAT driver of Linux, it updates free_clusters

Normally utime(2) checks current process is owner of the file, or it
has CAP_FOWNER capability. But FAT filesystem doesn't have uid/gid as
on disk info, so normal check is too unflexible.With this option you can relax it.

Many struct inode_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.Signed-off-by: Arjan van de Ven

This is a conversion to make the various file_operations structs in fs/
const. Basically a regexp job, with a few manual fixupsThe goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)Signed-off-by: Arjan van de Ven

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!
