[PATCH 2/3] cifs: enable fscache iff fsc mount option is used explicitly

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

 



Currently, if CONFIG_CIFS_FSCACHE is set, fscache is enabled on files opened
as read-only irrespective of the 'fsc' mount option. Fix this by enabling
fscache only if 'fsc' mount option is specified explicitly.

Remove an extraneous cFYI debug message and fix a typo while at it.
