Dave Chinner 5825294edd xfs: make inode flush at ENOSPC synchronous ... When we are writing to a single file and hit ENOSPC, we trigger a background flush of the inode and try again. Because we hold page locks and the iolock, the flush won't proceed until after we release these locks. This occurs once we've given up and ENOSPC has been reported. Hence if this one is the only dirty inode in the system, we'll get an ENOSPC prematurely. To fix this, remove the async flush from the allocation routines and move it to the top of the write path where we can do a synchronous flush and retry the write again. Only retry once as a second ENOSPC indicates that we really are ENOSPC. This avoids a page cache deadlock when trying to do this flush synchronously in the allocation layer that was identified by Mikulas Patocka.
