When we have multiple buffers in a single page for a blocksize == pagesize filesystem we might overwrite the page contents if two callers hit it shortly after each other. To prevent that we need to keep the page locked until I/O is completed and the page marked uptodate. Thanks to Eric Sandeen for triaging this bug and finding a reproducible testcase and Dave Chinner for additional advice. This should fix kernel.org bz #10421.

We only need to allocate space for the number of inodes in the cluster when writing back inodes, not every byte in the inode cluster. This reduces the amount of memory needing to be allocated to 256 bytes instead of 64k.

writeback If we allow memory reclaim to wait on the pages under writeback in inode cluster writeback we could deadlock because we are currently holding the ILOCK on the initial writeback inode which is needed in data I/O completion to change the file size or do unwritten extent conversion before the pages are taken out of writeback state.

由 David Chinner 提交于
xfs_fsync() fails to wait for data I/O completion before checking if the inode is dirty or clean to decide whether to log the inode or not. This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.

由 Christian Borntraeger 提交于
On kvm I have seen some rare hangs in stop_machine when I used more guest cpus than hosts cpus. e.g. 32 guest cpus on 1 host cpu triggered the hang quite often. I could also reproduce the problem on a 4 way z/VM host with a 64 way guest. It turned out that the guest was consuming all available cpus mostly for spinning on scheduler locks like rq->lock. This is expected as the threads are calling yield all the time. The problem is now, that the host scheduling decisings together with the guest scheduling decisions and spinlocks not being fair managed to create an interesting scenario similar to a live lock. (Sometimes the hang resolved itself after some minutes) Changing stop_machine to yield the cpu to the hypervisor when yielding inside the guest fixed the problem for me. While I am not completely happy with this patch, I think it causes no harm and it really improves the situation for me. I used cpu_relax for yielding to the hypervisor, does that work on all architectures? p.s.: If you want to reproduce the problem, cpu hotplug and kprobes use stop_machine_run and both triggered the problem after some retries.

The offset to the pt_regs area was wrong, so we weren't looking at the right location for the magic cookie.

Because of the silly way I set up the initial stack for new kernel threads, there is a loop at the top of the stack. To fix this, properly add another stack frame that is copied from the parent and terminate it in the child by setting the frame pointer in that frame to zero. Signed-off-by: NDavid S.

Unless there will be any objection here, I suggest consider the following patch which simply removes the code for the -DI_WISH_WORLD_WERE_PERFECT in the three methods which use it. The compilation errors we get when using -DI_WISH_WORLD_WERE_PERFECT show that this code was not built and not used for really a long time.
