Commit 3c3b177a9369 ("reservation: add support for read-only access
using rcu") introduced a sequence counter to manage updates to
reservations. Back then, the reservation object initializer
reservation_object_init() was always inlined.
Having the sequence counter initialization inlined meant
Asserting that preemption is enabled or disabled is a critical sanity
check. Developers are usually reluctant to add such a check in a

My prior fix went a bit too far, according to Herbert and Mathieu.
Since we accept that concurrent TCP MD5 lookups might see inconsistent

The seqcount_t latch reader example at the raw_write_seqcount_latch()

barrier and sequence counter comparison.

gdb.base/corefile.exp test in GDB's test suite.
In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel
This reverts commit 335d720bb4bd9d2808cae5af6f3c636c87f19596.
