[lustre-devel] [PATCH 09/30] lustre: obd: remove obsolete OBD_FL_LOCAL_MASK

[James Simmons]

From: Wang Shilong <wshilong at ddn.com>

Andreas Dilger reported that the OBD_FL_LOCAL_MASK support has
not been used since commit e62f0a3c5b9 b=21980 cache ll_obdo_cache:
Can't free all objects; which predates the linux client. With the
future landing of patch https://review.whamcloud.com/26463
lustre: quota: add project inherit attributes the handling of the
"local" flags is broken and since it is unused it is better to be
removed entirely.
