Linus Torvalds 548e7bcd0c A wide variety of mostly CephFS fixes and cleanups, split between
changes that address edge cases (Sam, Xiubo, Matthew), efficiency
 improvements (Max) and AI-assisted hardening (Michael, Jeremy).
 
 One thing that stands out is Alex's change to how CephFS behaves in
 NEARFULL scenarios: the long-standing "make all writes synchronous"
 behavior has become opt-in.  It was always somewhat controversial and
 doesn't make much sense for modern deployments; the new default is to
 continue normal operation (i.e. buffer writes as MDS allows, etc).  The
 behavior in case the cluster reaches any FULL state remains the same as
 before.
