mirror O_APPEND and O_DIRECT into iocb->ki_flags

2015-04-12T02:30:22+00:00

... avoiding write_iter/fcntl races.

switch generic_write_checks() to iocb and iter

2015-04-12T02:30:21+00:00

... returning -E... upon error and amount of data left in iter after
(possible) truncation upon success.  Note, that normal case gives
a non-zero (positive) return value, so any tests for != 0 _must_ be
updated.

fuse: ->direct_IO() doesn't need generic_write_checks()

2015-04-12T02:29:50+00:00

already done by caller.  We used to call __fuse_direct_write(), which
called generic_write_checks(); now the former got expanded, bringing
the latter to the surface.  It used to be called all along and calling
it from there had been wrong all along...

generic_write_checks(): drop isblk argument

2015-04-12T02:29:48+00:00

all remaining callers are passing 0; some just obscure that fact.

direct_IO: remove rw from a_ops->direct_IO()

2015-04-12T02:29:45+00:00

Now that no one is using rw, remove it completely.

direct_IO: use iov_iter_rw() instead of rw everywhere

2015-04-12T02:29:45+00:00

The rw parameter to direct_IO is redundant with iov_iter->type, and
treated slightly differently just about everywhere it's used: some users
do rw & WRITE, and others do rw == WRITE where they should be doing a
bitwise check. Simplify this with the new iov_iter_rw() helper, which
always returns either READ or WRITE.

make new_sync_{read,write}() static

2015-04-12T02:29:40+00:00

All places outside of core VFS that checked ->read and ->write for being NULL or
called the methods directly are gone now, so NULL {read,write} with non-NULL
{read,write}_iter will do the right thing in all cases.

expand __fuse_direct_write() in both callers

2015-04-12T02:27:53+00:00

it's actually shorter that way *and* later we'll want iocb in scope
of generic_write_check() caller.

fs: move struct kiocb to fs.h

2015-03-26T00:28:11+00:00

struct kiocb now is a generic I/O container, so move it to fs.h.
Also do a #include diet for aio.h while we're at it.
