That made functions like __d_drop() very fragile\nand non-obvious.\n\nIn particular, whether a dentry was hashed or not was indicated with an\nexplicit DCACHE_UNHASHED bit. That\u0027s despite the fact that the hash\nabstraction that the dentries use actually have a \u0027is this entry hashed\nor not\u0027 model (which is a simple test of the \u0027pprev\u0027 pointer).\n\nThe reason that was done is because we used the normal \u0027is this entry\nunhashed\u0027 model to mark whether the dentry had _ever_ been hashed in the\ndentry hash tables, and that logic goes back many years (commit\nb3423415fbc2: \"dcache: avoid RCU for never-hashed dentries\").\n\nThat, in turn, meant that __d_drop had totally different unhashing logic\nfor the dentry hash table case and for the anonymous dcache case,\nbecause in order to use the \"is this dentry hashed\" logic as a flag for\nwhether it had ever been on the RCU hash table, we had to unhash such a\ndentry differently so that we\u0027d never think that it wasn\u0027t \u0027unhashed\u0027\nand wouldn\u0027t be free\u0027d correctly.\n\nThat\u0027s just insane. It made the logic really hard to follow, when there\nwere two different kinds of \"unhashed\" states, and one of them (the one\nthat used \"list_bl_unhashed()\") really had nothing at all to do with\nbeing unhashed per se, but with a very subtle lifetime rule instead.\n\nSo turn all of it around, and make it logical.\n\nInstead of having a DENTRY_UNHASHED bit in d_flags to indicate whether\nthe dentry is on the hash chains or not, use the hash chain unhashed\nlogic for that. Suddenly \"d_unhashed()\" just uses \"list_bl_unhashed()\",\nand everything makes sense.\n\nAnd for the lifetime rule, just use an explicit DENTRY_RCUACCEES bit.\nIf we ever insert the dentry into the dentry hash table so that it is\nvisible to RCU lookup, we mark it DENTRY_RCUACCESS to show that it now\nneeds the RCU lifetime rules. Now suddently that test at dentry free\ntime makes sense too.\n\nAnd because unhashing now is sane and doesn\u0027t depend on where the dentry\ngot unhashed from (because the dentry hash chain details doesn\u0027t have\nsome subtle side effects), we can re-unify the __d_drop() logic and use\ncommon code for the unhashing.\n\nAlso fix one more open-coded hash chain bit_spin_lock() that I missed in\nthe previous chain locking cleanup commit.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b07ad9967f40b164af77205027352ba53729cf5a", "tree": "33ce9c53602f1983cff5dd5f209bb668fb7ffca5", "parents": [ "0f1d9f78ce41a8874d30271ef8480e6f8f7f1fce" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 23 22:32:03 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 23 22:32:03 2011 -0700" }, "message": "vfs: get rid of \u0027struct dcache_hash_bucket\u0027 abstraction\n\nIt\u0027s a useless abstraction for \u0027hlist_bl_head\u0027, and it doesn\u0027t actually\nhelp anything - quite the reverse.
