SubjectRe: wrong usage of __devexit_p and __exit_p

Actually the case I remembered here isn't part of the series.

In the meantime I checked this:

~/gsrc/linux-2.6$ git diff-tree -r linus/master expsec-master | cut -f 2 | xargs grep -h -E '__(dev)?exit_p'
.remove = __devexit_p(s3c_adc_remove),
.remove = __devexit_p(s3c_pwm_remove),
.remove = __devexit_p(virtblk_remove),
.remove = __devexit_p(virtrng_remove),
.remove = __devexit_p(stli_pciremove)
.remove = __devexit_p(hifn_remove),
.remove = __devexit_p(mpc85xx_pci_err_remove),
.remove = __devexit_p(mv64x60_pci_err_remove),
.remove = __devexit_p(max7301_remove),
.remove = __devexit_p(bbc_remove),
.remove = __devexit_p(grover_remove),
.remove = __exit_p(pxa_camera_remove),
.remove = __devexit_p(asic3_remove),
.remove = __devexit_p(ilo_remove),
.remove = __exit_p(mxcnd_remove),
.remove = __devexit_p(virtnet_remove),
.remove = __devexit_p(atp870u_remove),
.remove = __devexit_p(megaraid_detach_one),
.remove = __devexit_p(stex_remove),
.remove = __devexit_p(jsm_remove_one),
.remove = __devexit_p(sc26xx_driver_remove),
.remove = __devexit_p(spidev_remove),
.remove = __devexit_p(vhci_hcd_remove),
.remove = __devexit_p(virtballoon_remove),

So in the patched files __(dev)?exit_p is only used to fill struct
members. Provided this is the only usage of the respective
functions---and I checked that---it doesn't make sense that they don't
live in .devexit.text (or .exit.text respectively).

Does it make sence for you, too?

Best regards
