[PATCH 1/2] jffs2: Provide forced dirty node cleanup via POLL signal

Secure deletion under JFFS2 is complicated by the log of dirty nodes that may contain obsoleted versions of sensitive data. There is an existing mechanism to trigger a single gc step via -HUP signal; extend this to trigger gc collection of all currently-dirty data via a -POLL signal. On receipt o

[PATCH 2/2] jffs2: Provide jffs2_sync files to track gc POLL progress

When executing secure deletion under JFFS2 via the -POLL forced cleanup option, userspace may need to know when the process has safely completed. Provide debugfs files per mount that, when read, blocks while cleanup is in progress: once the read completes it is safe to assume that all obsoleted sen
