Each transaction maintains a global list of inodes to sync. It checks the inode and adds it in each write_end call per OS page. Locking and unlocking the global spinlock was showing up in profiles. At the very least, we can only get the lock once per large file that's written during a transaction. This will reduce spinlock traffic on the lock by the number of pages written per file. We'll want a better solution in the long run, but this helps for now. Signed-off-by: Zach Brown <zab@versity.com>
