Subject: cachefiles: narrow the scope of flushed requests when releasing fd
Git-commit: 65aa5f6fd8a12e0a343aaf1815949a79a49e3f35
Patch-mainline: v5.19-rc6
References: jsc#SES-1880
When an anonymous fd is released, only flush the requests
associated with it, rather than all of requests in xarray.
Fixes: 9032b6e8589f ("cachefiles: implement on-demand read")
