fs: Allow a NULL pos pointer to __kernel_write

2020-10-15T18:20:41Z

Linus prefers that callers be allowed to pass in a NULL pointer for ppos like new_sync_write(). Reviewed-by: Christoph Hellwig Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Al Viro

vfs: move the generic write and copy checks out of mm

2020-10-15T16:50:01Z

The generic write check helpers also don't have much to do with the page cache, so move them to the vfs. Signed-off-by: Darrick J. Wong

vfs: move the remap range helpers to remap_range.c

2020-10-15T16:48:49Z

Complete the migration by moving the file remapping helper functions out of read_write.c and into remap_range.c. This reduces the clutter in the first file and (eventually) will make it so that we can compile out the second file if it isn't needed. Signed-off-by: Darrick J. Wong

Now that import_iovec handles compat iovecs, the native readv and writev syscalls can be used for the compat case as well. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

2020-10-03T04:02:14Z

Now that import_iovec handles compat iovecs as well, all the duplicated code in the compat readv/writev helpers is not needed. Remove them and switch the compat syscall handlers to use the native helpers. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro
