um: switch cow_user.h to htobe{32,64}/betoh{32,64}

2012-04-09T22:13:45+00:00

... rather than open-coding the 64bit versions.  endian.h has those guys.

uml: arch/um/drivers formatting

2007-10-16T16:43:09+00:00

Style fixes for the rest of the drivers.  arch/um/drivers should be pretty
CodingStyle-compliant now.

Except for the ubd driver, which will have to be treated separately.

[PATCH] uml: fix patch mismerge

2006-05-02T01:17:44+00:00

I sent a patch, it was applied as cda402b283c34a24b091f78eee116963e9494762,
then it was applied again as 181ae4005d0a4010802be534d929b38c42b9ac06 by
mistake.  But while the 1st time it modified (correctly) cow_header_v3, the
2nd it modified cow_header_v3_broken.

[PATCH] uml: make 64-bit COW files compatible with 32-bit ones

2006-04-19T16:13:49+00:00

This is the minimal fix to make 64-bit UML binaries create 32-bit
compatible COW files and read them.

I've indeed tested that current code doesn't do this - the code gets
SIGFPE for a division by a value read at the wrong place, where 0 is
found.

[PATCH] uml: fix 2 harmless cast warnings for 64-bit

2006-04-11T13:18:35+00:00

Fix two harmless warnings in 64-bit compilation (the 2nd doesn't trigger for
now because of a missing __attribute((format)) for cow_printf, but next
patches fix that).

[PATCH] uml: safe migration path to the correct V3 COW format

2006-04-11T13:18:35+00:00

- Correct the layout of all header versions - make all them well-specified
  for any external event.  As we don't have 1-byte or 2-byte wide fields, the
  32-bit layout (historical one) has no extra padding, so we can safely add
  __attribute__((packed)).

- Add detection and reading of the broken 64-bit COW format which has been
  around for a while - to allow safe migration to the correct 32-bit format.
  Safe detection is possible, thanks to some luck with the existing format,
  and it works in practice.

[PATCH] uml: tidying COW code

2006-02-24T22:31:37+00:00

Improve (especially for coherence) some prototypes, and return code of
init_cow_file in error case - for a short write return -EINVAL, otherwise
return the error we got!

[PATCH] uml: correct error messages in COW driver

2006-02-24T22:31:36+00:00

Improve some error messages in the COW driver, and say V3, not V2, when
talking about V3 format.  Also resync with our userspace code utility a bit
more.
