By the time Linus Torvalds released the 5.2-rc1 kernel
prepatch and closed the
merge window for this development cycle, 12,064 non-merge changesets
had been pulled into the mainline repository — about 3,700 since our summary of the first “half” was written. Thus, as
predicted, the rate of change did slow during the latter part of the merge
window. That does not mean that no significant changes have been merged,
though; read on for a summary of what else has been merged for 5.2.
