Comment:
Thanks for your interest in the RTEMS port of JFFS2. If you have
questions, then you could also ask them on the de...@rtems.org mailing
list. The RTEMS port of JFFS2 does not use a file system internal locking.
There is a global lock for each JFFS2 instance:
{{{#!c
static void rtems_jffs2_do_lock(struct super_block *sb)
{
rtems_recursive_mutex_lock(&sb->s_mutex);
}
static void rtems_jffs2_do_unlock(struct super_block *sb)
{
rtems_recursive_mutex_unlock(&sb->s_mutex);
}
}}}
