Subject: [PATCH] misc: rename copy_file_range to copy_file_chunk
|
||
|
|
|
||
|
|
As of 2.27, glibc will have a copy_file_range library call to wrap the
|
||
|
|
new copy_file_range system call. This conflicts with the function in
|
||
|
|
misc/create_inode.c, which this patch renames _copy_file_range.
