Subject: [PATCH] fuse: fix mknod of regular file
X-Git-Tag: v2.6.20.14~23
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b9d493f10e0b20db0976506d4e3a31857d228051;p=thirdparty%2Fkernel%2Fstable.git

[PATCH] fuse: fix mknod of regular file

The wrong lookup flag was tested in ->create() causing havoc (error or
Oops) when a regular file was created with mknod() in a fuse
filesystem.

Thanks to J. Cameijo Cerdeira for the report.

Kernels 2.6.18 onward are affected.  Please apply to -stable as well.
