Subject: [PATCH v2 0/1] dcache: Translating dentry into pathname without taking rename_lock
Date: Thu, 5 Sep 2013 14:55:15 -0400 [thread overview]
Message-ID: <1378407316-59852-1-git-send-email-Waiman.Long@hp.com> (raw)
Change History
v1->v2:
- Check for internal vs external dname, taking d_lock only for
external dname for safety.
- Replace memchr() by a byte-by-byte checking for loop.
- Try lockless dentry to pathname conversion 3 times before falling
back to taking the rename_lock to prevent live-lock.
- Make code re-factoring suggested by George Spelvin.
