Hi Gautam,


Thank you for the patch.  'checkpatch.pl' complains as below, though:

	WARNING: Possible unwrapped commit description (prefer a maximum 75 chars per line)
	#12:
	Fix the warning - "Enum value 'NR_DAMON_OPS' not described in enum 'damon_ops_id'" generated by the command "make pdfdocs"

	WARNING: From:/Signed-off-by: email address mismatch: 'From: Gautam Menghani <gautammenghani14@...il.com>' != 'Signed-off-by: Gautam Menghani <gautammenghani201@...il.com>'

	total: 0 errors, 2 warnings, 7 lines checked

Could you please fix those?

I'd like to keep the 80 column limit[1].

[1] https://docs.kernel.org/process/coding-style.html#breaking-long-lines-and-strings

Also, strictly speaking, it's not the number of monitoring operations for _a
particular implementation_, but 'number of monitoring operations
implementations'.  And it's shorter.  How about the suggestion?


Thanks,
SJ
