Mohan Srinivasan	db94337285	ANDROID: Refactor fs readpage/write tracepoints. Refactor the fs readpage/write tracepoints to move the inode->path lookup outside the tracepoint code, and pass a pointer to the path into the tracepoint code instead. This is necessary because the tracepoint code runs non-preemptible. Thanks to Trilok Soni for catching this in 4.4.

Mohan Srinivasan	31f42471b1	ANDROID: fs: FS tracepoints to track IO. Adds tracepoints in ext4/f2fs/mpage to track readpages/buffered write()s. This allows us to track files that are being read/written to PIDs.

ANDROID: Refactor fs readpage/write tracepoints.

Refactor the fs readpage/write tracepoints to move the
inode->path lookup outside the tracepoint code, and pass a pointer
to the path into the tracepoint code instead. This is necessary
because the tracepoint code runs non-preemptible. Thanks to
Trilok Soni for catching this in 4.4.

Adds tracepoints in ext4/f2fs/mpage to track readpages/buffered
write()s. This allows us to track files that are being read/written
to PIDs.
