-===========

-If CONFIG_FSCACHE_OBJECT_LIST is enabled, the FS-Cache facility will maintain a
-list of all the objects currently allocated and allow them to be viewed
-through::
-
- /proc/fs/fscache/objects

-This will look something like::

-where the first set of columns before the '|' describe the object:
-
- ======= ===============================================================
- COLUMN DESCRIPTION
- ======= ===============================================================
- OBJECT Object debugging ID (appears as OBJ%x in some debug messages)
- PARENT Debugging ID of parent object
- STAT Object state
- CHLDN Number of child objects of this object
- OPS Number of outstanding operations on this object
- OOP Number of outstanding child object management operations
- IPR
- EX Number of outstanding exclusive operations
- READS Number of outstanding read operations
- EM Object's event mask
- EV Events raised on this object
- F Object flags
- S Object work item busy state mask (1:pending 2:running)
- ======= ===============================================================
-
-and the second set of columns describe the object's cookie, if present:
-
- ================ ======================================================
- COLUMN DESCRIPTION
- ================ ======================================================
- NETFS_COOKIE_DEF Name of netfs cookie definition
- TY Cookie type (IX - index, DT - data, hex - special)
- FL Cookie flags
- NETFS_DATA Netfs private data stored in the cookie
- OBJECT_KEY Object key } 1 column, with separating comma
- AUX_DATA Object aux data } presence may be configured
- ================ ======================================================
-
-The data shown may be filtered by attaching the a key to an appropriate keyring
-before viewing the file. Something like::
-
- keyctl add user fscache:objlist <restrictions> @s
-
-where <restrictions> are a selection of the following letters:
-
- == =========================================================
- K Show hexdump of object key (don't show if not given)
- A Show hexdump of object aux data (don't show if not given)
- == =========================================================
-
-and the following paired letters:
-
- == =========================================================
- C Show objects that have a cookie
- c Show objects that don't have a cookie
- B Show objects that are busy
- b Show objects that aren't busy
- W Show objects that have pending writes
- w Show objects that don't have pending writes
- R Show objects that have outstanding reads
- r Show objects that don't have outstanding reads
- S Show objects that have work queued
- s Show objects that don't have work queued
- == =========================================================
-
-If neither side of a letter pair is given, then both are implied. For example:
-
- keyctl add user fscache:objlist KB @s
-
-shows objects that are busy, and lists their object keys, but does not dump
-their auxiliary data. It also implies "CcWwRrSs", but as 'B' is given, 'b' is
-not implied.
-
-By default all objects and all fields will be shown.

A few references to the fscache object list were left in the Documentation, some arch defconfigs and in fs: remove them since this config does not exists anymore.
