This is a large patch to remove all dead code from obdclass and
ptlrpc, purely removing functions and declarations now, so
despite the size should be easy enough to verify.
Quite a bunch of them are only used on the server.
lu_object_put_nocache, lu_object_invariant, lu_dev_del_linkage,
lu_context_tags_update, lu_context_tags_clear, lu_session_tags_update,
lu_session_tags_clear, lu_env_refill_by_tags, lu_printk_printer,
lu_object_assign_fid, lu_object_anon, lu_buf_free, lu_buf_alloc,
lu_buf_realloc, lu_buf_check_and_alloc, lu_buf_check_and_grow
This function is only used on the server where real high-priority
requests actually exist.
This deletes ptlrpc_hpreq_handler() and ptlrpc_request_change_export()
staging/lustre/ptlrpc: Remove server-specific health checks
ptlrpc_service_health_check is only used on a service, so
it makes no point to retain it in the client code.
Also removing it's helpers: ptlrpc_svcpt_health_check and
ptlrpc_nrs_req_peek_nolock
Macro module_i2c_driver is used for drivers whose init
and exit paths does only register and unregister to i2c
API. Remove some boilerplate code by using module_i2c_driver.
The while() loop will only exit in a return or a goto ask_for_joinbss,
which means it will never break and execute the return after it.
Removing return _FAIL since it is dead code.

pmlmeinfo->ADDBA_req is accessed three times in this function, but it
contributes to generating lines above 80 characters that are not easy to
split in a nice way.
Extract a pointer to it to make code slightly more concise and fix some
lines over 80 characters.
staging: rtl8188eu: don't cast when calling rtw_set_fixed_ie()
The 'pbuf' and 'source' arguments to rtw_set_fixed_ie() are (void *), the
explicit typecasts are not needed. They just make code less readable.
Also fix checkpatch issues in the lines touched:
ERROR: space prohibited before that ',' (ctx:WxW)
WARNING: line over 80 characters
CHECK: Unnecessary parentheses around <var>
Note: some of the modified lines are still over 80 characters because they
are not fixable by just adding newlines. They will be fixed in a later
patch.
rtw_set_ie() is a memcpy-like function, taking addresses of memory buffers
among its parameters. Similarly to memcpy, change the parameters to be
void*. This will allow to get rid of typecasts whenever it is called.

staging/lustre: partially use time64_t for capa expiry
Here, we actually have a problem in 2038 or at the latest in 2106 when
the lc_expiry variable on the wire protocol overflows, including on
64-bit architectures.
Now that the actual code was removed, only on-the wire structure
is left so we add in a y2038 warning to remind whoever gets to
implement it again about this problem.
staging/lustre: Remove mds/ost capabilities support
Client capabilities is an outdated feature that never worked properly,
so let's get rid of the client support since modern servers
don't have this support either.
The patch is big, but since it just removes one large feature,
so it's hopefully easy to verify.
These particular helpers are unused so let's get rid of them:
ldebugfs_add_symlink, lprocfs_rd_u64, lprocfs_rd_atomic,
lprocfs_wr_atomic, lprocfs_rd_name, lprocfs_seq_read_frac_helper
Most of the code in llog.c and llog_cat.c is completely unused
on the client and can be removed, as a preparation for removing
the dt_object code.
Two tricky parts are:
- In llog_cat_close(), we rely on the fact that llh_flags never
contains LLOG_F_ZAP_WHEN_EMPTY, because nobody ever sets that
flag.
- In llog_read_header(), we check the return value of the lpi_cb
callback, and again we know that it cannot be LLOG_PROC_BREAK
or LLOG_DEL_RECORD and can remove the respective code path.
This is only used on the server to keep track of alive clients
and feeds into ping evictor (that was removed from the client code).
Also remove struct obd's obd_exports_timed and
struct obd_export's exp_obd_chain_timed used to keep track of that
staging/lustre: remove unused time handling functions
A bunch of API functions deal with time values but are now
completely unused in lustre. This removes them in order to
remove all references to time_t from the header files.
staging/lustre: remove wrappers for timer functions
This is a simple cleanup that I did after noticing that the abstraction
for the timer functions in completely pointless, and the one user (ptlrpc)
can just as well call the native Linux functions.
For good measure, this also removes the empty libcfs_arch_init()
and libcfs_arch_cleanup() functions that are defined in the
same file.
staging/lustre: use 64-bit times for request times
All request timestamps and deadlines in lustre are recorded in time_t
and timeval units, which overflow in 2038 on 32-bit systems.
In this patch, I'm converting them to time64_t and timespec64,
respectively. Unfortunately, this makes a relatively large patch,
but I could not find an obvious way to split it up some more without
breaking atomicity of the change.
Also unfortunately, this introduces two instances of div_u64_rem()
in the request path, which can be slow on 32-bit architectures. This
can probably be avoided by a larger restructuring of the code, but
it is unlikely that lustre is used in performance critical setups
on 32-bit architectures, so it seems better to optimize for correctness
rather than speed here.
Here we use an unsigned long to store the timeout for gc,
which is probably safe until 2106, but this patch converts it
to use ktime_get_real_seconds() and time64_t for consistency.
staging/lustre: use 64-bit times for ptlrpc sec expiry
The exp_flvr_expire and imp_sec_expire are defined as 'unsigned long',
which doesn't overflow until 2106, but to be on the safe side, this
changes the code to use time64_t like we do everywhere else.
These three are timestamps that are sent over the wire in mdc_lib
and the obd logging 64-bit values, but are generated using the 32-bit
get_seconds() function, which will eventually overflow.
Changing them to use 64-bit ktime_get_real_seconds() solves the problem.
staging/lustre: use 64-bit times in another debug print
The ll_setattr_raw() function prints the new inode timestamps
along with the current time using '%lu', which overflows in
2106. This changes the printing of the current time for
now, the other two will change when we migrate the VFS code
to use 64-bit timestamps.
staging/lustre: use 64-bit times in ptlrpc_enc_page_pool
ptlrpc_enc_page_pool computes time deltas using 'long' values from
get_seconds(). This is probably safe beyond y2038, but it's better
to go use monotonic times and 64-bit here for consistency.
staging/lustre: use 64-bit llite debugfs timestamps
The llite debugfs interface contains timestamps that are computed
from timeval, which overflows in 2038 on 32-bit systems.
This changes the output to use a timespec64 type to avoid the
overflow. I also change the format to print the sub-second portion
as 9 digits (nanoseconds) for clarity, rather than printing six
digits without leading zeroes.
