ab3fa89023 SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note() 
These APIs are used in sched_note.c to protect instumentation data.
The deffrence between these APIs to exsiting spin_lock() and spin_unlock()
is that they do not perform insturumentation to avoid recursive call
when SCHED_INSTRUMENTATION_SPINLOCKS=y.

e238c8b090 sched/clock/clock_systimer.c: Change the way that the 64-bit time is sampled. Previously, we disabled interrupts before sampling the 64-bit timer since the uint64_t access is not atomic on most CPUs. However, disabling (local) interrupts does not work in the SMP case. In that case, the timer interrupt will be running on only one of the CPUs; disabling interrupts on a different CPU will provide no protection from timer rollover. To work around this, logic was added that samples 64-bit timer is sampled twice and if 32-bit rollover was detected between samples, then loops until there is no rollover. 2018-01-15 11:05:45 -06:00

0ecef4dbcb clock_systimer: Replace critical section APIs with spinlock APIs. (64bit only) 
If SMP=n or SMP=y && SPINLOCK_IRQ=n, this works in the same way as before.
If SMP=y && SPINLOCK_IRQ=y, performance will be improved.

FAT. Effectively handles the situation when a new file position is within the current sector.

* Find begin of the next token

* EOL

* revert

* Accelerates the work of the FS with a multitude of operations to write small pieces of data within the current sector.
