NAME

inode_permission - check for access rights to a given inode

SYNOPSIS

int inode_permission(struct inode * inode, int mask);

ARGUMENTS

inode

inode to check permission on

mask

right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)

DESCRIPTION

Used to check for read/write/execute permissions on an inode. We use lqfsuidrq for this, letting us set arbitrary permissions for filesystem access without changing the lqnormalrq uids which are used for other things.
