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

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.
