H A D | fs_struct.c | c28cc364 Fri Jan 07 00:49:53 CST 2011 Nick Piggin <npiggin@kernel.dk> fs: fs_struct use seqlock
Use a seqlock in the fs_struct to enable us to take an atomic copy of the complete cwd and root paths. Use this in the RCU lookup path to avoid a thread-shared spinlock in RCU lookup operations.
Multi-threaded apps may now perform path lookups with scalability matching multi-process apps. Operations such as stat(2) become very scalable for multi-threaded workload.
