Arnd Bergmann c3b9cecd89 udf: convert inode stamps to timespec64
The VFS structures are finally converted to always use 64-bit timestamps,
and this file system can represent a long range of on-disk timestamps
already, so now let's fit in the missing bits for udf.

Deepa Dinamani 0220eddac6 udf: Simplify calls to udf_disk_stamp_to_time
Subsequent patches in the series convert inode timestamps
to use struct timespec64 instead of struct timespec as
part of solving the y2038 problem.

commit fd3cfad374 ("udf: Convert udf_disk_stamp_to_time() to use mktime64()")
eliminated the NULL return condition from udf_disk_stamp_to_time().
udf_time_to_disk_time() is always called with a valid dest pointer and
the return value is ignored.
Further, caller can as well check the dest pointer being passed in rather
than return argument.
Make both the functions return void.

This will make the inode timestamp conversion simpler.

Jan Kara d5bd821350 udf: Sanitize nanoseconds for time stamps
Reportedly some UDF filesystems are recorded with bogus subsecond values
resulting in nanoseconds being over 10^9. Sanitize nanoseconds in time
stamps when loading them from disk.

Jan Kara fd3cfad374 udf: Convert udf_disk_stamp_to_time() to use mktime64()
Convert udf_disk_stamp_to_time() to use mktime64() to simplify the code.
As a bonus we get working timestamp conversion for dates before epoch
and after 2038 (both of which are allowed by UDF standard).

Jan Kara 3c399fa40f udf: Use time64_to_tm for timestamp conversion
UDF on-disk time stamp is stored in a form very similar to struct tm.
Use time64_to_tm() for conversion of seconds since epoch to year, month,
... format and then just copy this as necessary to UDF on-disk
structure to simplify the code.

Joe Perches 78ace70c41 udf: Convert printks to pr_<level>
Use the current logging styles.

Convert a few printks that should have been udf_warn and udf_err.
Coalesce formats.  Add #define pr_fmt.
Move an #include "udfdecls.h" above other includes in udftime.c
so pr_fmt works correctly.  Strip prefixes from conversions as appropriate.
Reorder logging definitions in udfdecl.h

Marcin Slusarz 56774805d5 udf: convert udf_stamp_to_time and udf_time_to_stamp to use timestamps
* kernel_timestamp type was almost unused - only callers of udf_stamp_to_time
and udf_time_to_stamp used it, so let these functions handle endianness
internally and don't clutter code with conversions

* rename udf_stamp_to_time to udf_disk_stamp_to_time
  and udf_time_to_stamp to udf_time_to_disk_stamp

Cyrill Gorcunov b1e7a4b1bb UDF: coding style fixups
This patch does additional coding style fixup.  Initially the code is being
distorted by Lindent (in my patches sent not very long ago) and fixed in
the followup patches but this stuff was accidently missed.

New and old compiled files were compared with cmp to check for being
identically.  So the patch will not break the kernel.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
