* staging: exfat: remove staging version of exfat filesystemGreg Kroah-Hartman2020-03-101-760/+0
| | | | | | | | | | | | | | | | | | Now that there is a "real" solution for exfat in the vfs tree queued up to be merged in 5.7-rc1 the "old" exfat code in staging can be removed. Many thanks to Valdis for doing the work to get this into the tree in the first place, it was greatly appreciated.

* drivers/staging/exfat: Replace binary semaphores for mutexesDavidlohr Bueso2019-11-011-1/+1
| | | | | | | | | | | | | | | At a slight footprint cost (24 vs 32 bytes), mutexes are more optimal than semaphores; it's also a nicer interface for mutual exclusion, which is why they are encouraged over binary semaphores, when possible. For both v_sem and z_sem, their semantics imply traditional lock ownership; that is, the lock owner is the same for both lock/unlock operations. Therefore it is safe to convert.
