Hi,
With,
commit 1027abe8827b47f7e9c4ed6514fde3d44f79963c Author: Al Viro <viro@zeniv.linux.org.uk> Date: Wed Jul 30 04:13:04 2008 -0400
[PATCH] merge locate_fd() and get_unused_fd()
New primitive: alloc_fd(start, flags). get_unused_fd() and get_unused_fd_flags() become wrappers on top of it.
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
Two wrappers get_unused_fd() and get_unused_fd_flags() are introduced. get_unused_fd() is an exported one-liner:
int get_unused_fd(void) { return alloc_fd(0, 0); } EXPORT_SYMBOL(get_unused_fd);
But get_unused_fd_flags() is implemented through a macro:
#define get_unused_fd_flags(flags) alloc_fd(0, (flags))
Both are wrappers around alloc_fd(). I'm quite new to this stuff but why there's an asymmetry in here? One is exposed, the other is not.
(BTW: I'm doing compat-drm stuff for GSoC and I have to call get_unused_fd_flags() but since alloc_fd() is not exported, this doesn't work.)
Thanks :)
