Name:Handle a dentry that is managed in some way.* - Flagged for transit management (autofs)* - Flagged as mountpoint* - Flagged as automount point* This may only be called in refwalk mode.* On success path->dentry is known positive.
Proto:static int follow_managed(struct path *path, struct nameidata *nd)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct path * | path | |
| struct nameidata * | nd |
| 1222 | bool need_mntput = false |
| 1223 | ret = 0 |
| 1232 | If flags & manage transit from this dirent Then |
| 1236 | flags = smp_load_acquire( & protected by d_lock ) |
| 1237 | If ret < 0 Then Break |
| 1242 | If flags & s a mountpoint Then |
| 1243 | mounted = lookup_mnt(path) |
| 1244 | If mounted Then |
| 1261 | If flags & handle automount on this dir Then |
| 1262 | ret = Perform an automount* - return -EISDIR to tell follow_managed() to stop and return the path we* were called with. |
| 1263 | If ret < 0 Then Break |
| 1265 | Continue |
| 1269 | Break |
| 1272 | If need_mntput && mnt == mnt Then mntput(mnt) |
| 1274 | If need_mntput Then flags |= LOOKUP_JUMPED |
| 1278 | If ret > 0 && Value for the false possibility is greater at compile time(d_flags_negative(flags)) Then ret = -ENOENT |
| 1280 | If Value for the false possibility is greater at compile time(ret < 0) Then path_put_conditional(path, nd) |
| 1282 | Return ret |
