| H A D | splice.c | cc56f7de Wed Nov 04 02:09:52 CST 2009 Changli Gao <xiaosuo@gmail.com> sendfile(): check f_op.splice_write() rather than f_op.sendpage()
sendfile(2) was reworked with the splice infrastructure, but it still
checks f_op.sendpage() instead of f_op.splice_write() wrongly. Although
if f_op.sendpage() exists, f_op.splice_write() always exists at the same
time currently, the assumption will be broken in future silently. This
patch also brings a side effect: sendfile(2) can work with any output
file. Some security checks related to f_op are added too.
