Don't report Used Dev Size for RAID0.

2010-07-22T05:45:18+00:00

This number isn't meaningful for RAID0 as a different amount of space
might be used from each device.
It isn't meaningful for linear either, but already was not reported
for linear.
Detail doesn't report it either.
So make --examine not report it.

Cast to long long before left-shifting too much.

2010-07-22T05:35:54+00:00

When left-shifting we must be sure that the value being
shifted is large enough to not lose bits.
The 'chunkssize' in CreateBitmap is only 'long' so it
can overflow.  So cast to 'long long' first.

Also fix a similar issue in Detail even though it isn't currently
being compiled.

Incremental: restore assembly for inactive containers, block active

2010-07-19T21:59:25+00:00

GET_ARRAY_INFO always succeeds on an inactive container, so we need to
be a bit more diligent about adding a disk to an active container.

super-0.90: don't write bitmap larger than 60K

2010-07-07T11:31:33+00:00

The 4K superblock can be as close as 64K from the end
of the device.  As the bitmap (with header) lives after
the superblock (with 0.90 metadata) there could be as
little as 60K of space.
So limit the bitmaps to 59.5K, and only write 60K including
the header.

The bug fixed here means that bitmaps cannot be created
on devices which are exact multiples of 64K in size

imsm: fix a -O2 build warning

2010-07-06T19:48:59+00:00

super-intel.c: In function ‘imsm_add_spare’:
super-intel.c:4833: error: ‘array_start’ may be used uninitialized in this function
super-intel.c:4834: error: ‘array_end’ may be used uninitialized in this function

This is valid, if we don't find a spare candidate then array_{start,end}
will be uninitialized.

mdmon: satisfy glibc tls abi requirements with pthreads

2010-07-06T19:48:56+00:00

Setting up a proper tls descriptor is required to conform to the abi
[1].  Until it can be implemented in mdmon use pthreads instead of
clone(2) to let glibc handle the details.  The old behaviour can be had
by un-defining USE_PTHREADS.

Note, the "O2" builds need LDFLAGS now to pick up the '-pthread' option.

Fix the count of member devices in mdstat_read function.

2010-07-06T08:02:22+00:00

Correction of the number of container or volume member devices (devcnt
in struct mdstat_ent). The number after the last devices was counted
towards member of devices.
