- Handle buffer lock waiters count directly in the buffer cache instead
than rely on the lockmgr support [1]: * bump the waiters only if the interlock is held * let brelvp() return the waiters count * rely on brelvp() instead than BUF_LOCKWAITERS() in order to check for the waiters number - Remove a namespace pollution introduced recently with lockmgr.h including lock.h by including lock.h directly in the consumers and making it mandatory for using lockmgr. - Modify flags accepted by lockinit(): * introduce LK_NOPROFILE which disables lock profiling for the specified lockmgr * introduce LK_QUIET which disables ktr tracing for the specified lockmgr [2] * disallow LK_SLEEPFAIL and LK_NOWAIT to be passed there so that it can only be used on a per-instance basis - Remove BUF_LOCKWAITERS() and lockwaiters() as they are no longer used This patch breaks KPI so __FreBSD_version will be bumped and manpages updated by further commits. Additively, 'struct buf' changes results in a disturbed ABI also. [2] Really, currently there is no ktr tracing in the lockmgr, but it will be added soon.
