[PATCH v3 7/7] NFSD: Deprecate NFS_OFFSET_MAX

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



NFS_OFFSET_MAX was introduced way back in Linux v2.3.y before there
was a kernel-wide OFFSET_MAX value. As a clean up, replace the last
few uses of it with its generic equivalent, and get rid of it.
