Use syscall! for copy_file_range too 2020-11-16T19:31:12+00:00 Josh Stone jistone@redhat.com 2020-11-05T22:09:28+00:00 urn:sha1:cd22381daa7f23bf20a739ac35c95ff77921d9a0 Always handle EOVERFLOW by falling back to the generic copy loop 2020-11-13T21:38:27+00:00 The8472 git@infinite-source.de 2020-11-12T22:39:49+00:00 urn:sha1:bbfa92c82debed28417350b15fc6a2f46135346d Previously EOVERFLOW handling was only applied for io::copy specialization but not for fs::copy sharing the same code. Additionally we lower the chunk size to 1GB since we have a user report that older kernels may return EINVAL when passing 0x8000_0000 but smaller values succeed. do direct splice syscall and probe availability to get android builds to work 2020-11-13T21:38:27+00:00 The8472 git@infinite-source.de 2020-11-06T22:36:23+00:00 urn:sha1:4854d418a5245b07eca7dbec92a29d18af13a821 Android builds use feature level 14, the libc wrapper for splice is gated on feature level 21+ so we have to invoke the syscall directly. Additionally the emulator doesn't seem to support it so we also have to add ENOSYS checks. move sendfile/splice/copy_file_range into kernel_copy module 2020-11-13T21:38:27+00:00 The8472 git@infinite-source.de 2020-10-15T01:07:57+00:00 urn:sha1:3dfc377aa12293ace29f9a055f0aeb634d107ed9 limit visibility of copy offload helpers to sys::unix module 2020-11-13T21:38:27+00:00 The8472 git@infinite-source.de 2020-10-14T23:51:47+00:00 urn:sha1:888b1031bc267132c66dbba49b43a55a83452ca4
