vfs: Make d_invalidate return void

2014-10-09T06:38:57+00:00

Now that d_invalidate can no longer fail, stop returning a useless
return code.  For the few callers that checked the return code update
remove the handling of d_invalidate failure.

vfs: Remove unnecessary calls of check_submounts_and_drop

2014-10-09T06:38:56+00:00

Now that check_submounts_and_drop can not fail and is called from
d_invalidate there is no longer a need to call check_submounts_and_drom
from filesystem d_revalidate methods so remove it.

fuse: honour max_read and max_write in direct_io mode

2014-09-27T01:16:51+00:00

The third argument of fuse_get_user_pages() "nbytesp" refers to the number of
bytes a caller asked to pack into fuse request. This value may be lesser
than capacity of fuse request or iov_iter.  So fuse_get_user_pages() must
ensure that *nbytesp won't grow.

Now, when helper iov_iter_get_pages() performs all hard work of extracting
pages from iov_iter, it can be done by passing properly calculated
"maxsize" to the helper.

The other caller of iov_iter_get_pages() (dio_refill_pages()) doesn't need
this capability, so pass LONG_MAX as the maxsize argument here.

switch iov_iter_get_pages() to passing maximal number of pages

... instead of maximal size.

fs: call rename2 if exists

2014-08-07T18:40:09+00:00

Christoph Hellwig suggests:

1) make vfs_rename call ->rename2 if it exists instead of ->rename
2) switch all filesystems that you're adding NOREPLACE support for to
   use ->rename2
3) see how many ->rename instances we'll have left after a few
   iterations of 2.

fuse: add FUSE_NO_OPEN_SUPPORT flag to INIT

2014-07-22T14:37:43+00:00

Here some additional changes to set a capability flag so that clients can
detect when it's appropriate to return -ENOSYS from open.

This amends the following commit introduced in 3.14:

  7678ac50615d  fuse: support clients that don't implement 'open'

However we can only add the flag to 3.15 and later since there was no
protocol version update in 3.14.

Default s_time_gran is 1, don't overwrite that if userspace didn't
explicitly specify one.
