Subject: [PATCH] NFSv4_2: SSC helper should use its own config.
|
|
|
|
Currently NFSv4_2 SSC helper, nfs_ssc, incorrectly uses GRACE_PERIOD
|
|
as its config. Fix by adding new config NFS_V4_2_SSC_HELPER which
|
|
depends on NFS_V4_2 and is automatically selected when NFSD_V4 is
|
|
enabled. Also removed the file name from a comment in nfs_ssc.c.
