2015-11-13s3: smbd: Change aio_pending_size static variable to a new "aio max threads" ↵Jeremy Allison1-20/+2
smb.conf parameter. Removes accessor functions as now this parameter is set under user control in smb.conf. Default is 100. Note that this doesn't limit the number of outstanding aio requests, it just causes them to go onto the pthreadpool queue. Now we need to prioritize pthreadpool pipe replies ahead of incoming SMB2 requests, but that's a patch for another day. Based on ideas from Volker.

2012-04-12Fix the same bug reported by Kirill Malkin ↵Jeremy Allison1-4/+24
<kirill.malkin@starboardstorage.com> and fixed by Volker for vfs_aio_fork as ref 0aacdbfada46329e0ad9dacfa90041a1c7dbf3e8. From that change: aio_suspend does not signal the main process with a signal, it just waits. The aio_fork module does not use the signal at all, it directly calls back into the main smbd by calling smbd_aio_complete_aio_ex. This is an abstraction violation, but the alternative would have been to use signals where they are not needed. However, in wait_for_aio_completion this bites us: With aio_fork we call handle_aio_completed twice on the same aio_ex struct: Once from the call to handle_aio_completion within the aio_fork module and once from the code in wait_for_aio_completion. Fix this differently here by not calling directly back into smbd, but using a new function aio_linux_setup_returns() to setup the return values that wait_for_aio_completion() in the main smbd will pick up by calling handle_aio_completd().
