2020-09-27Clean up kcov.Dean Deng
Previously, we did not check the kcov mode when performing task work. As a result, disabling kcov did not do anything. Also avoid expensive atomic RMW when consuming coverage data. We don't need the swap if the value is already zero (which is most of the time), and it is ok if there are slight inconsistencies due to a race between coverage data generation (incrementing the value) and consumption (reading a nonzero value and writing zero).

2020-09-24[vfs] kernfs: Do not hold reference on the inode when opening FD.Ayush Ranjan
The FD should hold a reference on the dentry they were opened on which in turn holds a reference on the inode it points to. PiperOrigin-RevId: 333589223

2020-09-23fuse: don't call dentry.InsertChildAndrei Vagin
It is called from the kernfs code (OpenAt and revalidateChildLocked()). For RemoveChildLocked, it is opposed. We need to call it from fuse.RmDir and fuse.Unlink. PiperOrigin-RevId: 333453218

2020-09-21Allow partial writes for gofer.specialFileFD.Dean Deng
Originally, we avoided partial writes in case it caused us to write a partial packet to a socket-backed specialFileFD. However, this check causes splicing from a pipe to specialFileFD to fail if we hit EOF on the pipe. PiperOrigin-RevId: 333016216
