This patchset adds some fixes for output buffers: 1) Always return the number of bytes that we effectively copied; 2) Make sure we never block if O_NONBLOCK is passed. With 2) some refactoring was done on the loop which makes it (IMHO) a bit neater. Also note all of this is by code inspection and not really tested on a real system. Even though the changes are fairly trivial, I do intend to run a small test to make sure nothing basic broke. Since I was touching this file, I jut felt I could fix all the checkpatch complains :) Nuno Sá (3): iio: buffer: correctly return bytes written in output buffers iio: buffer: make sure O_NONBLOCK is respected iio: buffer: fix coding style warnings drivers/iio/industrialio-buffer.c | 119 +++++++++++++++--------------- 1 file changed, 61 insertions(+), 58 deletions(-) -- 2.39.2
