Hi Al, this series fixes a few issues and cleans up the helpers that read from or write to kernel space buffers, and ensures that we don't change the address limit if we are using the ->read_iter and ->write_iter methods that don't need the changed address limit. I did not add your suggested comments on the instances using uaccess_kernel as all of them already have comments. If you have anything better in mind feel free to throw in additional comments. Changes since v4: - warn on calling __kernel_write on files not open for write - add a FMODE_READ check and warning in __kernel_read - add a new patch to remove kernel_readv - stop preferring the iter variants if normal read/write is present Changes since v3: - keep call_read_iter/call_write_iter for now - don't modify an existing long line - update a change log Changes since v2: - picked up a few ACKs Changes since v1: - __kernel_write must not take sb_writers - unexport __kernel_write Diffstat: fs/autofs/waitq.c | 2 fs/cachefiles/rdwr.c | 2 fs/read_write.c | 171 ++++++++++++++++++++++++++----------------- fs/splice.c | 53 +++---------- include/linux/fs.h | 4 - net/bpfilter/bpfilter_kern.c | 2 security/integrity/iint.c | 14 --- 7 files changed, 125 insertions(+), 123 deletions(-)
