e2c4399e28 More precise disk usage time 
When we wait, we now count the time for all the waiting disks,
and not only for the first one that finish.

56bef0d90f Fix an invalid assumption about allocated parity 
In the copy detection it's possible to need to
copy from a file wihout parity. This could result
in the parity position not found.

2e12b10590 Signal condition variables outside the lock 
This reduces the number of context switches, because the
signaled thread can start immediately.

Some interesting discussion is at:

Condvars: signal with mutex locked or not?

Calling pthread_cond_signal without locking mutex

8e47e2b024 Signal the 'done' condition only at the waiting index

e69e8640ce Use pread also in import and search 2016-01-09 10:25:56 +01:00
Andrea Mazzoleni
18cc80bd7e Now pread and pwrite use is required for multithread 
We need to support concurrent access at the same file handle
from multiple threads, and they cannot share the same file pointer.

0849bfc261 Use a thread-safe pread/pwrite implementation for Windows 
This may be useful in future for concurrent calls to the same file.

b619b9bee1 Use a faster memory test 
We have now many buffers to test, and we need a faster test.

cbf2040b89 Add mutex protection at the filesystem structure 
In sync we need to modify the filesystem, like to call
fs_deallocate(). We need then proper protection.
This also removes the need of multiple fs_last cached value.
