ovl_follow_link current calls ->put_link on an error path. However ->put_link is about to change in a way that it will be impossible to call it from ovl_follow_link. So rearrange the code to avoid the need for that error path. Specifically: move the kmalloc() call before the ->follow_link() call to the subordinate filesystem.

由 Mario Kleiner 提交于
Since commit 844b03f2 we make sure that after vblank irq off, we return the last valid (vblank count, vblank timestamp) pair to clients, e.g., during modesets, which is good. An overlooked side effect of that commit for kms drivers without support for precise vblank timestamping is that at vblank irq enable, when we update the vblank counter from the hw counter, we can't update the corresponding vblank timestamp, so now we have a totally mismatched timestamp for the new count to confuse clients. Restore old client visible behaviour from before Linux 3.17, but zero out the timestamp at vblank counter update (instead of disable as in original implementation) if we can't generate a meaningful timestamp immediately for the new vblank counter. This will fix this regression, so callers know they need to retry again later if they need a valid timestamp, but at the same time preserves the improvements made in the commit mentioned above.
