Modified files: sys/kern vfs_bio.c Log: For low memory situations, non-VMIO buffers didnt't release pages back to the system when brelse() was called with B_RELBUF set on the buffer. This could be a problem when the system was low on memory, had many buffers on QUEUE_EMPTYKVA and started to traverse directories. For each getnewbuf(), pages were allocated from the system, driving the free reserve downwards. For each brelse(), the system put the buffer on QUEUE_CLEAN, with B_INVAL set. This commit changes the semantics of B_RELBUF to also free pages from non-VMIO buffers.
