NAME

generic_permission - check for access rights on a Posix-like filesystem

SYNOPSIS

int generic_permission(struct inode * inode, int mask, int (*check_acl) (struct inode *inode, int mask));

ARGUMENTS

inode

inode to check access rights for

mask

right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)

check_acl

DESCRIPTION

Used to check for read/write/execute permissions on a file. We use "fsuid" for this, letting us set arbitrary permissions for filesystem access without changing the "normal" uids which are used for other things..
