Mdassemble improvements
From: Luca Berra <bluca@comedia.it> - Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele stacked arrays. - Allow mdassemble, when run a second time, to mark all arrays as writable. This is useful if they are started read-only as is best at boot-time.

|
|||
- Reduce maximum bitmap usage when working with bitmap files,
|
||||
so that a only single-page allocations are made, even on
|
||||
64bit hosts with 4K pages.
|
||||
- Close stray fd in mdassemble so that it can assemble stacked
|
||||
devices
|
||||
- If mdassemble finds an array already assembled, it marks it
|
||||
read-write.
|
||||
|
||||
Changes Prior to 2.5.4 release
|
||||
- When creating devices in /dev/md/ create matching symlinks
