Linus Torvalds 478a1469a7 Filesystem DAX locking for 4.7 ... - We use a bit in an exceptional radix tree entry as a lock bit and use it similarly to how page lock is used for normal faults. This fixes races between hole instantiation and read faults of the same index. - Filesystem DAX PMD faults are disabled, and will be re-enabled when PMD locking is implemented. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXRKwLAAoJEJ/BjXdf9fLB+BkP/3HBm05KlAKDklvnBIPFDMUK hA7g2K6vuvaEDZXZQ1ioc1Ajf1sCpVip7shXJsojZqwWmRz0/4nneF7ytluW9AjS dBX+0qCgKGH1fnwyGFF+MN7fuj7kGrSDz34lG0OObRN6/oKiVNb2svXiYKkT6J6C AgsWlWRUpMy9jrn1u/FduMjDhk92Z3ojarexuicr0i8NUlBClCIrdCEmUMi4orSB DuiIjestLOc7+mERBUwrXkzoh9v8Z0FpIgnDLWwpeEkAvJwWkGe5eXrBJwF+hEbi RYfTrOYc7bBQLo22LRb8pdighjrx3OW9EpNCfEmLDOjM3cYBbMK/d2i/ww52H6IK Mw6iS5rXdGgJtQIGL8N96HLFk+cDyZ8J8xNUCwbYYBJqgpMzxzVkL3vTm72tyFnl InWhih+miCMbBPytQSRd6+1wZG2piJTv6SsFTd5K1OaiRmJhBJZG47t2QTBRBu7Y 5A4FGPtlraV+iDJvD6VLO1Tp8twxdLluOJ2BwdGeiKXiGh6LP+FGGFF3aFa5N4Ro xSslCTX7Q1G66zXQwD4+IMWLwS1FDNymPkUSsF6RQo6qfAnl9SrmYTc4xJ4QXy92 sUdrWEz2OBTfxKNqbGyc/KrXKZT3RnEkJNft8snB2h6WTCdOPaNYs/yETUwiwkSc CXpuQFrxm69QYwNsqVu1 =Pkd0 -----END PGP SIGNATURE----- Merge tag 'dax-locking-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull DAX locking updates from Ross Zwisler: "Filesystem DAX locking for 4.7 - We use a bit in an exceptional radix tree entry as a lock bit and use it similarly to how page lock is used for normal faults.
