Hello,
you may remember that I reported regression in VM. I used you filecache module and discovered that the leaks are caused by these items: # filecache 1.0 # ino size cached cached% refcnt state dev file 167302 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167301 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167300 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167299 4 4 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167290 8 8 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167289 8 8 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167288 16 16 100 1 -- 00:08(tmpfs) /drm\040mm\040object\040(deleted) 167287 16 16 100 1 d- 00:08(tmpfs) /drm\040mm\040object\040(deleted)
there are tons of those items: cat /proc/filecache | grep drm | wc -l 14224
Do you have any clues what happens here? Is it a bug in kernel VM system or it is more likely a bug in Intel's GEM drm driver? Right now it results in 500MB of undropable cache.
Also lsof reports many leaked file descriptors: lsof | grep drm | wc -l 7326
