Thomas Schoebel-Theuer 0c7bb9d00f if: fix bio flags for newer kernels 
The old code was just bullshit.

Thomas Schoebel-Theuer e4e9308310 if: improve performance of big bio requests 
Writethrough of bio requests having more than one biovec should
only sync the last one. The others will be written to the transaction
log anyway. No need to wait for each of them to be committed one
by one.

Thomas Schoebel-Theuer 8f6054b0cc trans_logger: call _flush_inputs() more often 
The old behaviour could lead to starvation effects.
In particular, direct IO writes were affected.

Daniel Hermann 92951e491b marsadm: improve primary/secondary command behaviour 
Previously, the 'marsadm primary' and 'marsadm secondary' commands
were successful as soon as the target primary was successfully set
to the new primary or '(none)', respectively.  This commit appends
a check to wait until the primary is really changed (actual state).

Changes in marsadm:
- Added check_primary_settled() function
- Do not use local variable named '$host' in _primary_res() since
  a global variable with same name exists.
- Do not use/set global variable '$host' in primary_res().  Use
  local variable '$new' initially set to '$host' instead.
- Make 'secondary' command idempotent ("is already secondary")
- Call trigger() and check_primary_settled() in primary_res()

Related minor changes:
- marsadm: Added optional parameter 'sleeptime' to sleep_timeout()
- Removed debug output in check_file_aged()

Thomas Schoebel-Theuer 814b92ba19 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.
