[PATCH RFC PKS/PMEM 39/58] fs/jffs2: Utilize new kmap_thread()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Ira Weiny <ira.weiny@xxxxxxxxx>

These kmap() calls are localized to a single thread.  To avoid the over head of
global PKRS updates use the new kmap_thread() call.
