resized but still had dirty pages to be written back, vm_cache_resize() (which is called with the inode lock being held) deadlocked with the page writer. * Now, I reintroduced busy_writing: it'll be set by everything that writes back pages (vm_page_write_modified(), and the page writer), and will be checked for in vm_cache_resize() - other functions are not affected for now, AFAICT. * vm_cache_resize() will clear that flag, and the writer will check it again after it wrote back the page (which will fail when it's outside the file bounds), and if it's cleared, it will get rid of the page (if the file has been resized again in the mean time, writing it will succeed then, and we'll keep the page around). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23334 a95241bf-73f2-0310-859d-f6bbb57e9c96 |
