aio: fix race on file length (workaround)
...
It appears that concurrent reads and writes on AIO seem to
result in inconsistent reads in some very rare cases, due to
races. Sometimes, the inode claims that the file has been already
appended by a write operation, but the data has not actually hit
the page cache, such that a concurrent read gets NULL blocks.
This is a workaround by "misusing" the mapfree infrastructure.
It depends on uniqueness of file names, which is not the right thing
to do.
Best fix would be in the kernel.

marsadm: use actual primary where appropriate instead of target primary
...
The actual primary is decoded in 'actual-*/is-primary' links, while the
target primary is decoded in the 'primary' link. This is not clearly
taken into account in several functions of marsadm. This commit fixes
this problem.
- Added _get_actual_primary() function
- Remove $pri parameter in _primary_res
- Use _get_actual_primary() where actual state should be used
