Description David Smith 2015-06-11 14:27:16 UTC 
On rawhide (4.1.0-0.rc7.git0.1.fc23.x86_64), the vfs.do_sync_{read,write} probe alias no longer work since those functions were removed from the kernel by the following commit:

    kill do_sync_read/do_sync_write
    
    all remaining instances of aio_{read,write} (all 4 of them) have explicit
    ->read and ->write resp.; do_sync_read/do_sync_write is never called by
    __vfs_read/__vfs_write anymore and no other users had been left.
