More details on this in the patch. - finally, change VFS to pass ppos=NULL into .read/.write for files that declare themselves streams. It was suggested by Rasmus Villemoes and makes sure that if ppos starts to be erroneously used in a stream file, such bug won't go unnoticed and will produce an oops instead of creating illusion of position change being taken into account. Note: this patch does not conflict with "fuse: Add FOPEN_STREAM to use stream_open()" that will be hopefully coming via FUSE tree, because fs/fuse/ uses new-style .read_iter/.write_iter, and for these accessors position is still passed as non-pointer kiocb.ki_pos . * tag 'stream_open-5.2' of https://lab.nexedi.com/kirr/linux: vfs: pass ppos=NULL to .read()/.write() of FMODE_STREAM files *: convert stream-like files from nonseekable_open -> stream_open dtlk: remove double call to nonseekable_open		2019-05-07 12:15:13 -07:00
