* staging: exfat: remove staging version of exfat filesystemGreg Kroah-Hartman2020-03-101-514/+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.

| | | | | | | | | | buf_cache_t.flag is used only for lock. Change the variable name from 'flag' to 'locked' and remove unused definitions.

* staging: exfat: Remove FAT/VFAT mount support, part 3Valdis Kletnieks2019-11-131-188/+19
| | | | | | | | | | | | | In this patch, we straighten out most of the cases where the code was testing 'p_fs->vol_type == EXFAT' and '!= EXFAT' There's still some ?: ops and a few places where the code is doing checks for '.' and '..' that require looking at, but those are future patches Signed-off-by: Valdis Kletnieks <Valdis.Kletnieks@vt.edu> Link: https://lore.kernel.org/r/20191112211238.156490-4-Valdis.Kletnieks@vt.edu Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* drivers/staging/exfat: Replace more binary semaphores with mutexesDavidlohr Bueso2019-11-021-24/+24
| | | | | | | | | | | | | | | | 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. There is also lockdep support. For both f_sem and b_sem, their semantics imply traditional lock ownership; that is, the lock owner is the same for both lock/unlock operations and not under irq contexts (ie for trylock/unlock scenarios). Therefore it is safe to convert.

* staging: exfat: add exfat filesystem code to stagingValdis Klētnieks2019-08-301-0/+722
The exfat code needs a lot of work to get it into "real" shape for the fs/ part of the kernel, so put it into drivers/staging/ for now so that it can be worked on by everyone in the community.
