Several corrections apply to this section.
For the nfs_32_time_ok symbol, do the following.
Change the symbol name to nfs_allow_preepoch_time.
Change the description to, "This symbol controls whether the NFS client or server allows file timestamps that precede 1970."
No change to the default description.
Delete the nfs_acl_cache symbol entry.
Add an nfs_disable_rddir_cache symbol entry.
Description: Some servers do not properly update the attributes of the directory when changes are made. To allow interoperability with these broken servers, set this variable to disable the readdir cache.
Default: Set to off(0).
For the nfs_lookup_neg_cache and nfs3_lookup_neg_cache symbols, do the following.
Change the default to 1. Ignore the comment about the directory name caching.
For the nrnode symbol, do the following.
Change the default description to set to ncsize. By setting the variable to 1, you are effectively disabling the cache, not because an explicit check reveals whether or not the variable 1 but because you are creating a very small cache.
For the nfs_write_error_interval symbol, do the following.
Change the description to, "This symbol controls how often NFS ENOSPC and EDQUOT write error messages are logged. The symbols units are in seconds."
No change to the default description.
