Subject: simpler calling conventions for filename_mountpoint()
X-Git-Tag: fixes-v4.0-rc1~75^2~3
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cbaab2db9103cc6727c7166d2fda9f64038c828c;p=pandora-kernel.git

simpler calling conventions for filename_mountpoint()

a) make it accept ERR_PTR() as filename (and return its PTR_ERR() in that case)
b) make it putname() the sucker in the end otherwise

simplifies life for callers...
