for_each_set_bitrange(9)

✨ NAME ✨

okay so welcome to the for_each_set_bitrange(9) page from the Kernel API Manual, bestie 💖 — this one is literally about one job: iterate over all set bit ranges [b; e). iconic behavior, no cap ✨

💅 SYNOPSIS 💅

the signature is right here, fr fr:

for_each_set_bitrange (b , e , addr , size );

🎀 ARGUMENTS 🎀

these four are the whole squad 🫶:

• b — bit offset of start of current bitrange (first set bit) ✨
• e — bit offset of end of current bitrange (first unset bit) 💅
• addr — bitmap address to base the search on 🦋
• size — bitmap size in number of bits 🌸

🦋 SEE ALSO 🦋
