netfs: Add a function to consolidate beginning a read
Add a function to do the steps needed to begin a read request, allowing
this code to be removed from several other functions and consolidated.
netfs: Add a function to consolidate beginning a read
Add a function to do the steps needed to begin a read request, allowing
this code to be removed from several other functions and consolidated.
Changes
=======
ver #2)
- Move before the unstaticking patch so that some functions can be left
static.
- Set uninitialised return code in netfs_begin_read()[1][2].
- Fixed a refleak caused by non-removal of a get from netfs_write_begin()
when the request submission code got moved to netfs_begin_read().
- Use INIT_WORK() to (re-)init the request work_struct[3].

netfs: Refactor arguments for netfs_alloc_read_request

Also add a parameter to indicates the origin of the request. Ceph can use
this to tell whether to get caps.
Changes
=======
ver #3)
- Change the author to me as Jeff feels that most of the patch is my
changes now.
ver #2)
- Show the request origin in the netfs_rreq tracepoint.

netfs: Define an interface to talk to a cache
Add an interface to the netfs helper library for reading data from the
cache instead of downloading it from the server and support for writing
data just downloaded or cleared to the cache.
The API passes an iov_iter to the cache read/write routines to indicate the
data/buffer to be used. This is done using the ITER_XARRAY type to provide
direct access to the netfs inode's pagecache.
When the netfs's ->begin_cache_operation() method is called, this must fill
in the cache_resources in the netfs_read_request struct, including the
netfs_cache_ops used by the helper lib to talk to the cache. The helper
lib does not directly access the cache.
Changes:
v6:
- Call trace_netfs_read() after beginning the cache op so that the cookie
debug ID can be logged[3].
- Don't record the error from writing to the cache. We don't want to pass
it back to the netfs[4].
- Fix copy-to-cache subreq amalgamation to not round up as it goes along
otherwise it overcalculates the length of the write[5].
v5:
- Use end_page_fscache() rather than unlock_page_fscache()[2].
v4:
- Added flag to netfs_subreq_terminated() to indicate that the caller may
have been running async and stuff that might sleep needs punting to a
workqueue (can't use in_softirq()[1]).
- Add missing inc of netfs_n_rh_read stat.
- Move initial definition of fscache_begin_read_operation() elsewhere.
- Need to call op->begin_cache_operation() from netfs_write_begin().

netfs: Add tracepoints
Add three tracepoints to track the activity of the read helpers:
(1) netfs/netfs_read
This logs entry to the read helpers and also expansion of the range in
a readahead request.
(2) netfs/netfs_rreq
This logs the progress of netfs_read_request objects which track
read requests. A read request may be a compound of multiple
subrequests.
(3) netfs/netfs_sreq
This logs the progress of netfs_read_subrequest objects, which track
the contributions from various sources to a read request.
