6 This option enables support for network filesystems, including
7 helpers for high-level buffered I/O, abstracting out read
8 segmentation, local caching and transparent huge page support.
11 bool "Gather statistical information on local caching"
12 depends on NETFS_SUPPORT && PROC_FS
14 This option causes statistical information to be gathered on local
15 caching and exported through file:
17 /proc/fs/fscache/stats
19 The gathering of statistics adds a certain amount of overhead to
20 execution as there are a quite a few stats gathered, and on a
21 multi-CPU system these may be on cachelines that keep bouncing
22 between CPUs. On the other hand, the stats are very useful for
23 debugging purposes. Saying 'Y' here is recommended.
