- Don't cache unreferenced glocks: when a glock is no longer referenced (for example, because the inode it protects is evicted), it is now released as soon as possible instead of leaving it around until memory pressure or an unmount forces it out. For some workloads, this saves a lot of memory and speeds up unmounts significantly. - Harden gfs2_glock_hold() by making sure the caller holds a reference and fix a related race in checking for the liveliness of glocks between gdlm_bast() and gfs2_glock_cb(). -----BEGIN PGP SIGNATURE----- iQJIBAABCgAyFiEEJZs3krPW0xkhLMTc1b+f6wMTZToFAmqC7e8UHGFncnVlbmJh QHJlZGhhdC5jb20ACgkQ1b+f6wMTZTql+A/+OLEPtizpJ6k/uqk7+I63D0xYakK5 GMWCPPf5C9fernW57cF/p0TfRRDUKqKOrb+mKkJuPBMSfEZIldKOmYQx6U/kvXIF 6hdtRfAvVBjIs1aY+P/dliRXfzvO1HVamPsu7dx7NdTnozJz2tv/spNQ2cZV5tQD 2t6VovUzje+U7x7Qsz3EhN/po1aNBlXlzWtvF/r7uwAtiYfXaknJkr8cjo202w0Y fAQ5KRZA5EiN1Fc1d6V7ehYyzv31osmaQA9Bsf7NVlpnBPG1LyibYWzFF4zg1pDo 9JU4tcD9IpIALwYkGFFcG1qutjq0E2QKqeYgaIau94ezQnTY+q1zQQDiixyoHxHu 2AHMIcbUzEKHib+pYWtSy5GLgeTI59+hxFe9tOERhjHGDW8fYbqQTV969S84bYTm +Ar04VsbToMdjYSh5I+FPLQbKwfetKjDIlKSYeZzMOfGEqpJtoU9lB8WbvP/2LcQ c5hJfJcV7JWW9j4YZZIZuwzZv93CstBvFubKpktMw0x9utGc6a7M+f9eADYnd3JH l7yb+dyjUeYeIqEbALsfnxicuoiYfVKNVxh/zdz4TJEYDH1l/CyBIirLsSAVTAJl ruCT13akq5e+EXGOztcIXyU39l/ajJA0v58n9gzEzMakTwpyCTwx7WcooILf1aem P1QRnAoud8FoAYk= =U72j -----END PGP SIGNATURE----- Merge tag 'gfs2-for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull gfs2 updates from Andreas Gruenbacher: - Don't cache unreferenced glocks: when a glock is no longer referenced (for example, because the inode it protects is evicted), it is now released as soon as possible instead of leaving it around until memory pressure or an unmount forces it out.
