Hello, conversion of UDF to use the same address_space operations for normal an inline (in-ICB) files had two bugs resulting in buffered reads / writes not really working properly for in-ICB files. Interestingly none of the xfstests discovered this (likely because files have to be small to fit within ICB and you have to evict the first file page from the page cache to notice). I've now verified with manual testing that read & writes to in-ICB files work again after these fixes. I plan to push these fixes to Linus through my tree soon. Honza
