for_each_set_bit_wrap(9)

🎀 NAME 🎀

okay so bestie, welcome to this page — it's for_each_set_bit_wrap(9) from the Kernel API Manual, and the whole assignment is literally to iterate over all set bits starting from @start, and wrapping around the end of bitmap. it's giving circular-bitmap main character energy, no cap. 💅✨

✨ SYNOPSIS ✨

the call looks exactly like this, bestie:

for_each_set_bit_wrap (bit , addr , size , start );

💅 ARGUMENTS 💅

here's the little squad you're passing in:

• bit — offset for current iteration. that's your current loop spot, bestie.
• addr — bitmap address to base the search on.
• size — bitmap size in number of bits.
• start — Starting bit for bitmap traversing, wrapping around the bitmap end.
